Question

MIA has a rectangle of cloth.she dips the top5/8 of cloth in blue dye.she dips the bottom 9/20 of the cloth in yellow dye.the part of cloth dips in both turns green.wirk out fraction that turns green.

Answer 1

Converting the fractions into decimals will give you 0.625 and 0.45. Adding these decimals together will give you 1.075 telling you the dyes overlapped. Because the sum is over 100% the remainder, 0.075, would be the part that turns green.

0.075 as a fraction would be 3/40.

So I believe your answer is 3/40.

Answer 2

To see the total parts of the cloth, you need to have a common denominator.

5/8 * 5/5 = 25/40

9/20 * 2/2 = 18/40

The total cloth is 40/40. The top 25 parts were dyed blue, the bottom 18 parts were dyed yellow. 25+18 = 43

So 3/40 of the cloth is yellow+blue = green
