Answer 1

The value of x is 7

Solution:

Given that we have to solve the proportion

`(9)/(10) = (9x)/(70)`

We can solve the proportion by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

Therefore,

`(9)/(10) = (9x)/(70)\\\\9 * 70 = 9x * 10\\\\x * 10 = 70\\\\x = 7`

Thus value of "x" is 7
