3/4 x 30 = 90/4 = 22.5
i think 30 over 72
30
If you mean (2/5 times 30) minus (4/3 times 15/8) then the answer is 19/2 or 9.5
5/3 x 4/5 x 3/2 = 60/30 = 2
15/8 times 2/1 = 30/8 = 15/4 or 3 and 3/4 = 3.75
4/3 x 9/10 = 36/30 or 1 and 1/5
3/4 and 20/30 does not make a proportion. 20/30 = 2/3 3/4 does not equal 2/3 so it is not a proportion.
It is: a/3 times b/4 = ab/12
5*64/15 = 5*6 + 5*4/15 (using the distributive property of multiplication over addition). = 30 + 4/3 = 30 + 11/3 = 311/3
4/5 x 5/6 = 20/30 or 2/3 2/3 x 9/8 = 18/24 or 3/4
9/16
3/17
