How do you turn percents into fractions?

Answers

Step 1: You want to remove the percent sign and then put the number over 100.

Step 2: If the percent is not a whole number then you want to multiply the top and bottom number by 10 but only for every number that comes after the decimal point.

Step 3: Always simplify if possible.

Examples:

43% = [tex]\frac{43}{100}[/tex]

78% = [tex]\frac{78}{100}[/tex] = [tex]\frac{39}{50}[/tex]

0.4% = [tex]\frac{0.4}{100}[/tex] = [tex]\frac{4}{1000}[/tex] = [tex]\frac{1}{250}[/tex]

Converting percents to fractions involves writing the percent as a fraction with a denominator of 100 and then simplifying. For example, 75% is equivalent to 75/100, which simplifies to 3/4. Decimals can be converted to percents by multiplying by 100 and adding the percent sign.

Converting Percents to Fractions

To convert a percent to a fraction, start by writing the percent value as a fraction with a denominator of 100. For example, 75% would be written as 75/100. The next step is to simplify the fraction if possible. To simplify, you find the greatest common divisor (GCD) of the numerator and the denominator and divide both by this number. For instance, the GCD of 75 and 100 is 25, so when we divide both the numerator and the denominator by 25, we get 3/4. Hence, 75% as a fraction in simplest terms is 3/4.

When converting to decimals, simply divide the numerator by the denominator. So, 75% becomes 0.75 when turned into a decimal. Conversely, to convert a decimal to a percent, you multiply by 100 and add the percent symbol (%). For instance, converting the decimal 0.75 to a percent, you would calculate 0.75 * 100 which equals 75%, completing the conversion.

Calculating percents is about understanding the ratio or fraction that the percent represents. The term 'percent' literally means 'per hundred', so any percent can be thought of as that number over 100. For example, 3% means 3/100 and 100% represents a whole or 1 as it's equivalent to 100/100.

just multiply 9 and 6 which gives you your answer 54.

so out of 54, he has graded only 12 pages which means that you need to subtract.

driscoll has 42 pages left to grade.

you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right.

Haruka hiked several kilometers in the morning in the morning. She only hiked 6 kilometers in the afternoon, which was 25% less she had hiked in the morning. How many kilometers did haruka hike in all?

Answers

Given that Haruka hiked only 25% less in the afternoon, this means that in the afternoon she hikes 75% of the distance she hiked in the morning. This 75% of a certain number is equal to 6. To determine the distance she hiked in the morning, we represent it as x and use the equation,
 
             0.75x = 6

The value of x from the equation is 8. Adding together the 6 and 8 will give us an answer of 14.

Answer: 14 kilometers

The complete distance Haruka hiked can be calculated by converting the percent to decimal.

The total distance is 14 km Haruka hike in all.

Given:

She hiked in afternoon is [tex]6\: \rm km[/tex].

Let the distance hiked in morning is [tex]x[/tex].

As per the question, 6 kilometers 25% less she had hiked in morning.[tex]\begin{aligned}\left(\dfrac{100\%-25\%}{100}\right)x&=6\\0.75x&=6\\x&=\dfrac{6}{0.75}\\x&=8\\\end[/tex]

Therefore, Haruka hiked [tex]8\:\rm km[/tex] in morning.

Calculate the total distance hiked.

[tex]\rm Total\: distance=8+6=14 \:\rm km[/tex]

Thus, the total distance is 14 Km Haruka hike in all.

How many 3/4 cup servings are in 1/2 of a cup of milk? Write your answer in simplest form.

Answers

The answer to this question would be: 0.375 cups of milk

In this question, you are asked how many cups of milk is 3/4 serving from 1/2 cup of milk. To answer this, you need to multiply the number of serving with the serving size.
If one serving is 1/2 cups of milk, then 3/4 servings would be:
3/4 servings * (0.5 cups / serving)= 3/8 cups of milk = 0.375 cups of milk

The number of 3/4 cup servings that are in 1/2 of a cup of milk is [tex]\frac{2}{3}[/tex]

In order to determine the number of 3/4 cup servings that are in 1/2 cup of milk, divide the fraction of the cup of milk by the fraction of cup servings

Cup of milk ÷ Number of cup servings

= [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{3}{4}[/tex]

[tex]\frac{1}{2}[/tex] x [tex]\frac{4}{3}[/tex]

= [tex]\frac{4}{6}[/tex]

In order to express the answer in its simplest form, divide the numerator by two and the denominator by 2. The numerator and the denominator are both divided by two because two is a common factor of 4 and 6

= [tex]\frac{2}{3}[/tex]

The answer is 40.67 dollars

Hope this helps
Final answer:

The Pesos you would get if you exchanged $121.10 using an exchange rate of $3 = 1 Peso, you can set up a proportion and solve for x.

Explanation:

To calculate how many Pesos you would get if you exchanged $121.10 at an exchange rate of $3 = 1 Peso, you can set up a proportion:

$3 / 1 Peso = $121.10 / x Pesos

Cross multiply to solve for x:

$3 * x = $121.10 * 1
