Answer 1

Answer:

7

Step-by-step explanation:

Let the number be added to the each term be -x

According the question-

2+x / 3+x = 9/10

10( 2+x ) = 9( 3+x )

20+ 10x = 27+9x

10x - 9x = 27 - 20

x = 7

There fore to be added in each term of the ratio 2:3 to make ratio = 9:10

check answer-

Put the value of x = 7

2+7/3+7= 9/10
