Oliver and Peter had the same length of string. Oliver used 3/4 of his string to tie a bundle of newspaper. Peter used 6/8 of his string to tie a bundle of magazines. Did they use the same amount of string.

Yes.

Step-by-step explanation:

3/4 = 6/8. We know this, because 3/4 can be doubled to equal 6/8.

3/4 × 2/2 = 6/8. Likewise,

6/8 ÷ 2/2 = 3/4.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
