To multiple fractions, multiple the numerators (top numbers) together, and the denominators (bottom numbers) together, and simplify the result:
-8/9 x -4/7 = 32/63
5/8 x 4/7 is 5/14
5/8 x 4/7 is 5/14.
7/8 x 4/5 = 28/40 or 7/10
2 8/7 divided by 4/7 is the same as 8/7 times 7/4... The 7s then cancel out and you get 8/4 which is 2
(4/3)*(6/7) = 8/7
Anything times 1 is the number you started with.
1/8
28/40 or 7/10
7 / 8 x 4 / 14 7 x 4 = 28 8 x 14 = 112 28 / 112 same as 1 / 4
5/8 x 4/7 is 5/14
4/4 x 7/8 This is what i think it looks like by your explanation. Ok so 4x7=28, 4x8=32 so it is 28 over 32 which is 7 over 8...--7/8.
1 7/8 x 4/5 is 1 1/2 or 1.5
