Question

2/3=x/15= what is the missing proportion

Answer 1

The value of "x" is 10

Solution:

Given that, we have to find the missing proportion

The given proportion is:

$\frac{2}{3} = \frac{x}{15}$

We can solve the above proportion by cross multiplying

Multiply the numerator of the first fraction by the denominator of the second fraction

Multiply the numerator of the second fraction by the denominator of the first fraction

Solve for variable "x"

$\frac{2}{3} = \frac{x}{15}\\\\2 \times 15 = x \times 3\\\\30 = 3x\\\\\text{Divide both sides of equation by 3}\\\\x = 10$

Thus the missing number is 10
