3/5 x 5/12 x 4/15 = 3 x 5 x 4/5 x 12 x 15= 5 x (3 x 4)/5 x 12 x 15= 1/15
3/4
(2/3) * (4/5) = 8/15
15/28
(5/x) * (3/4) = (5*3)/(x*4) = 15/4x
3/5 x 5/12 x 4/15 = 3 x 5 x 4/5 x 12 x 15= 5 x (3 x 4)/5 x 12 x 15= 1/15
3/4
(2/3) * (4/5) = 8/15
15/28
15 over 28
(5/x) * (3/4) = (5*3)/(x*4) = 15/4x
1/6 * 4/5 = 4/30 = 2/15
Yes, you can, because 15 goes into 15 once and 60 4 times, so it is simplified to 1 over 4. If you don't know your 15 times table, or cannot see 15 in 15 over 60, you can use 5 - 5 goes into 15 3 times and 5 goes into 60 12 times, so it is 3 over 12, whih can be simplified by dividing by 3. 3 goes into 3 once and 3 goes into 12 4 times so it is 1 over 4.
If that's 22 and 4/5 x 2/3, the answer is 228/15 = 76/5 or 15 and 1/5
8/15 x 9/4 = 1 1/5
(24/5)(-4/3) (-96/15) =-6 2/5
5x over 4 = 3 + 3 over 4 = 15 over 4 5x over 4 = 15 over 4 times both sides by 4 5x = 15 divide both sides by 5 x = 3
