Question

Divide * 351 into two parts such that the ratio of the two parts is 2 : 7?​

Answer 1

Step-by-step explanation:

so let those parts be = 7x and 2x

now their sum will be = 351

7x+2x = 351

9x = 351

x = 351/ 9

x = 39

so 2x = 2 (39) = 78

and 7x = 7 (39) = 273

Answer 2

Step-by-step explanation:

Let the common ratio between the two be x.

Then, 2:7 will be 2x and 7x respectively.

Now,

2x+7x= 351 (A/Q)

9x=351

x=351/9

x= 39

2x= 2*39=78

7x= 7*39=273

Verification = 78+273=351
