Question

the least number to be added to each term of ratio 7:12 to make the ratio 2:1 is​

Answer 1

Answer:

-17

Step-by-step explanation:

The ratio of two no's 7:13

After adding one term, the ratio becomes 2:1

(7 + x) / (12 + x) = 2    ( 2 / 1 =2)

7 + x = 2(12 + x)

7 + x = 24 + 2x

7 - 24 = x

x = -17

Tell me if it's right :)
