Question

find the value of x in each of the following proportions (show process)
8:10 = x:50

Answer 1

Answer:

40

Step-by-step explanation:

8:10=x:50

8/10=x/50

$\frac{8}{10} = \frac{x}{5 \times 10}$

$x = \frac{5 \times 8 \times 10}{10}$

x= 40

Answer 2

The value of x in the proportion is 8:10 = 40:50.

Step-by-step explanation:

To find the value of x; we first convert the ratio to fractions:

8:10 = $\frac{8}{10}$

x:50 = $\frac{x}{50}$

as 8:10 = x:50; the fractions are also equal;

$\frac{8}{10} = \frac{x}{50}$

cross multiplying:

$\frac{8 * 50}{10} = x$

x = 8 * 5

x = 40.

So the proportions can be written as:

8:10 = 40:50
