1) 3/4 x 5/6 = 3×5 / 4×6 = 15/24 = 5/8

2) 5 1/3 x 7 1/2 = 16/3 x 15/2 = 240/6 = 40

5/8: numerator of first and denominator of second could be reduced (both divided by 3), so 3/4 x 5/6 became 1/4 x 5/2. Then multiply across (1×5 and 4×2) and you get 5/8. Do it the long way and get 15/24, then reduce down (divide by common number of 3) and get 5/8.

40: 5 1/3 equals 16/3. 7 1/2 equals 15/2. 16/3 x 15/2. Use the same process as the first to reduce down: 8/1 x 5/1…or 8 x 5. Equals 40.

Took me a minute to remember what to do, and I’m sure I don’t have the terminology right! Yay for the return of AYSTASG!

Ok, so you multiple the tops across and the bottoms across so – 15/24 simplified = 5/8

And the other one, you get them both in fraction form and do the same thing – 240/6 simplified =40!
