Question

What must be added to each term of ratio 3:5,so that it becomes 4:5​

Answer 1

Answer:

The ratio of 56:70=4:5.

Step-by-step explanation:

Let the numbers be 3x and 5x

By adding y to each of them the ratio becomes 4:5. Or.

(3x+y):(5x+y) = 4:5 or

5(3x+y) = 4(5x+y), or

15x + 5y = 20x + 4y, or

5x = y.

Suppose x = 1, the original numbers are 3 and 5 and the revised numbers by addition of 5 become 3+5 or 8 and 5+5 or 10 and the ratio of the two revised numbers is thus 8:10 or 4:5.

The ratio of 56:70=4:5.
