Answer:

$\text{ \large \underline{ \red{Question}}}$

• X :15 :: 21 : 28 find X value

$\text{ \large \underline{ \green{Given}}}$

• X :15 :: 21 : 28

$\text{ \large \underline{ \pink{To Find}}}$

• find value of x

$\text{ \large \underline{ \orange{Solution}}}$

$\sf \to \: \frac{x}{15} = \frac{21}{28} \\ \\ \sf \to \: 28x = 21 \times 15 \\ \\ \sf \to \: \: \: \: \: \: x = \frac{21 \times 15}{28} \\ \\ \sf \to \: \: \: \: \: \: x \: = \frac{3 \times 15}{4} \\ \\ \sf \to \red{ \: \: \: \: \: x \: = 11.25}$

$\text{ \large\purple{Hence the value of x is 11.25}}$

$\text{ \large \underline{ \green{verification:}}}$

$\sf \to \: \frac{11.25}{15} = \frac{21}{28} \\ \\ \sf \to \: \frac{21 \times 15}{11.25 \times 28} \\ \\ \sf \to \frac{3 \times 15}{11.25 \times 4} \\ \\ \sf \to \frac{45}{45} \\ \\ \sf \to \pink{ \: 0}$
