Must be in the same units
6 ft/ 24 ft (8yds x 3 = 24 ft)

Let's use yards instead
6 ft = 2 yds
so
2 yds/8 yds again is 1/4
3/4 - 3/5
common denominator is 20
15/20 - 12/20 = 3/20
3/20 is your answer
multiply the opposite denominator with current numerator to get your new numerator number
hope this helps
Answer:
15 green pieces.
Step-by-step explanation:
8x = 24
x = 3.
So you need 3 times the amount of green pieces for every yellow piece.
3 * 5 green pieces = 15 green pieces
Well you can add to find out that 9 x 5 = 45 and 1/2 x 5 = 2 1/2 so the correct answer is 47 1/2 to estimate it just do 9 x 5 = 45 Hope this helps! :D
