Answers
Answer 1
567 your answer is 567
Answer 2
Red = 1/4 Blue = 2/3 Yellow= ?
First you will need to find how much of the fraction is yellow so: RED= 1/4 = 3/12 BLUE= 2/3 = 8/12 YELLOW= add 3/12 with 8/12= 11/12 12/12 - 11/12= 1/12
so the yellow marbles are 1/12
yellow + red = 120 1/12 + 3/12= 120 4/12= 120
so 4/12 of the marbles are 120
how much is 8/12? 120 x 2= 240
now: red + yellow = 120 blue= 240
how many are in the bag? 120 + 240 = 360
answer: 360
I don't know if this is correct. but I tried. hope this helped:)

60. 60 + 60 + 60 = 180.
x + (x+1) + (x+2) + (x+3) = 180 4x + 6 = 180 4x = 174 x = cannot be an even integer If they were consecutive even integers, x + (x+2) + (x+4) + (x+6) = 180 4x + 12 = 180 4x = 168 x = 42, 44, 46, 48
