6 / (4/5) = 6 * (5/4) = 30/4 = 15/2 or 7.5
(15/4) / (6/5) = (15/4) * (5/6) = (15*5)/(4*6) = 25/8
4/(5/6) is the same as 4*(6/5). Which is 24/5. You would then do the same and add it to the next part. So 6/(5/4). Is the same as 6*(4/5) which is 24/5. Now add the two. Your answer is 48/5. ALTERNATE: OR, if you instead meant (4/5)/6 + (6/5)/4, then this would be the same as (1/6) * (4/5) + (1/4)*(6/5) = (4/30) + (6/20). From here, you can simplify to (2/15) + (3/10). The common multiple of 15 and 10 is 30, so we multiply (2/15) by (2/2) and multiply (3/10) by (3/3) which gives us: 4/30 + 9/30 = 13/30 Remember, division is NOT associative! 4/(5/6) does NOT equal (4/5)/6, so you need to describe your question accurately, or else you might get the wrong answer from us!
1/4 (simplified from 15/60)
1/10 + 1/4 + 1/5 + 2/15 = 6/60 + 15/60 + 12/60 + 8/60 = 41/601/10 + 1/4 + 1/5 + 2/15 = 6/60 + 15/60 + 12/60 + 8/60 = 41/601/10 + 1/4 + 1/5 + 2/15 = 6/60 + 15/60 + 12/60 + 8/60 = 41/601/10 + 1/4 + 1/5 + 2/15 = 6/60 + 15/60 + 12/60 + 8/60 = 41/60
You have:[ ( 6 ) ( 4 ) ] / [ 15 ] = [ 24 ] / [15 ] = [ 8 ] / [ 5 ] = 8/5 = 1 3/5
4/6-2/5=4/15. 4/6-2/5=20/30-12/30=8/30=4/15
6 / (4/5) = 6 * (5/4) = 30/4 = 15/2 or 7.5
2/5 = 6/15 + 4/15 = 10/15 = 2/3
1/6 * 4/5 = 4/30 = 2/15
4 over 10 and 6 over 15
13/15 − 4/6 = 18/90 which reduces to 1/5
(15/4) / (6/5) = (15/4) * (5/6) = (15*5)/(4*6) = 25/8
4/9 = 8/18 5/6 = 15/18 8/18 + 15/18 = 23/18
6/15 = 2/5 = 4/10 = 40%. So 6/15 = 40%
3/2 x 5/6 = 15/12 = 5/4 or 1 and 1/4
(1/3) + (4/10) = (5/15) + (6/15) = 11/15
