Question

What quantity must be subtracted from each term of the ratio 9:17 to make it equal to 1:3

Answer 1

Let x should be subtracted,



According to the question, Subtracting x from each term,


⏩▶
$\frac{9 - x}{17 - x} = \frac{1}{3} \\ \\ \\ = > 3(9 - x) = 17 - x \\ \\ \\ = > 27 - 3x = 17 - x \\ \\ \\ = > 27 - 17 = 3x - x \\ \\ \\ = > 10 = 2x \\ \\ \\ = > \frac{10}{2} = x \\ \\ \\ = > 5 = x$




Hence, 5 should be subtracted.

Answer 2

we know

1/3= 2/6= 3/9= 4/12= 5/15

you can do any of the following

9-8/17-14

9-7/17-11
