Answer 2

12 : 16 = x : 28

Form the fractions

➾ $\dfrac{12}{16} = \dfrac{x}{28}$

Reducing the 1st fraction by 4,

➾ $\dfrac{3}{4} = \dfrac{x}{28}$

Cross - multiply

➾ 28 × 3 = x × 4

Multiply

➾ 84 = 4x

Switch the sides

➾ 4x = 84

Find x

➾ x = $\dfrac{84}{4}$

➾ x = 21


∴ The value of x is $\blue{\boxed{\blue{\boxed{\green{\mathbb{21}}}}}}$


Verification :-

$\dfrac{12}{16} = \dfrac{x}{28}$

➾ $\dfrac{3}{4} = \dfrac{x}{28}$

➾ 28 × 3 = x × 4

➾ 84 = 4x

➾ 4x = 84

➾ 4 × 21 = 84

➾ 84 = 84

∴ LHS = RHS ✔✔
