Question

What is the least number to be subtracted from each term in the ratio 15:35 to make it

2:7?​

Answer 1

Answer:

Step-by-step explanation:

according to question equation =

$\frac{15 - x}{35 - x} = \frac{2}{7}$

after cross multiplication

7(15-x)  = 2(35-x)

105 - 7x = 70 - 2x

105 - 70 = -2x + 7x

35 = 5x

x = 35/5

x = 7
