Question

Tap the correct answer:
$\frac{180}{3}÷\frac{12}{3}=$

• A. $12$
• B. $20$
• C. $15$

Answer 1

The correct option is C $15$

Step 1: Turn the second fraction upside down (it becomes a reciprocal)
$\frac{12}{3}$ becomes $\frac{3}{12}$

Step 2: Multiply the first fraction by that reciprocal. Multiply the top numbers and the bottom numbers as follows.

$\therefore \frac{180}{3}\times \frac{3}{12}=\frac{180\times 3}{3\times 12}$

Step 3: Simplify the fraction

$=\frac{2\times 2\times 3\times 3\times 5\times 3}{3\times 2\times 2\times 3}$
($\because$ Common factor gets canceled)

$=5\times 3$

$=15$

Hence,
$\frac{180}{3}÷\frac{12}{3}=15$
