Three fifths of a is equal to five eighths of B. the ratio of B to a is ()
Let a x, B y
3/5X=5/8Y
24X=25Y
X:Y=25:24
Four fifths of the number a is equal to three eighths of the number B. what is the number a?
A is 3 / 8 / 4 / 5 of B = 15 / 32
If you understand and solve your problem,
8 / 7 of a equals 2 / 5 of B. the number of a is 21. What's the number of B?
21 ×8/7 ÷2/5
= 24 ÷2/5
=60 B
7 / 8 of the number a is equal to 2 / 3 of the number B, and the number B is 21
21×2/3÷7/8=16
