Question

Find the third proportional to 1/2 and 3/4​

Answer 1

The answer is 9/8

GIVEN

Fractional numbers; 1/2 and 3/4

TO FIND

Third proportional to the given fractional numbers.

SOLUTION

We can simply solve the above problem as follows;

We are given proportional fractions;

1/2 : 3/4

Let the third proportional number be x

Now,

$\frac{1}{2} : \frac{3}{4} :: \frac{3}{4} :x$

We know that,

Product of means = Product of extremes

$\frac{1}{2} x = \frac{9}{16}$

$x = \frac{9}{16} \times 2$

x = 9/8

Hence, The answer is 9/8
