Question

What value of x will make this proportion true x/35= 3/7?

Answer 1

x/35 = 3/7.....cross multiply
(7)(x) = (3)(35)
7x = 105
x = 105/7
x = 15

Answer 2

15.

Explanation:

We have the proportion

`(x)/(35)=(3)/(7)`

using the cross multiplication we have that

7x =3*35

7x = 105

x = 105/7

x = 15.

Then, with x=15 we have that the proportion

`(15)/(35)=(3)/(7)`

is true. You can check it, if you divide the numerator and the denominator of 15/35 by 5, you will obtain 3/7.
