Question

4 1/2 ÷ 1 1/4 = a b/c

Answer 1

Here is the equation:

$4 \frac{1}{2} \div 1 \frac{1}{4} = a \frac{b}{c}$

When you're going to be dividing fractions, you have to keep, change, and flip. Also, make sure you make the fractions improper when it's a mixed number.

$4 \frac{1}{2} = \frac{9}{2}$

$1 \frac{1}{4} = \frac{5}{4}$

Now keep, change, flip

$Keep\ \frac{9}{2} \\ Change \div to\ \times \\ Flip\ \frac{5}{4} = \frac{4}{5}$

Your new equation is:

$\frac{9}{2} \times \frac{4}{5}$

Multiply:

$\frac{9}{2} \times \frac{4}{5} = \frac{36}{10} = 3 \frac{6}{10} \rightarrow 3 \frac{3}{5}$

Your answer is:

$3 \frac{3}{5} \\ a = 3 \\ b = 3 \\ c = 5$
