Question

the difference of two number is 9 if and the ratio is of 42 the 7 find the number​

Answer 1

Step-by-step explanation:

Let 1st number = x

2nd number = 9+x

A.T.Q

(9+x)/(x)=42/7

we write it in this way because sum of 9+x is larger than x and 42 is larger than 7.

(9+x)×7=42×(x)

63+7x=42x

42x-7x=63

35x=63

x=63/35

=> x=9/5

=> 1st number = 9/5

=> 2nd number = 9+(9/5) = 54/5
