Question

What is 2/7 ÷ 4/21 fully reduced

Answer 1

When dividing fractions, you flip the second fraction and multiply

$\dfrac{2}{7} \div \dfrac{4}{21}~becomes~\dfrac{2}{7}*\dfrac{21}{4}$

Next, we multiply:

$\dfrac{2}{7}*\dfrac{21}{4}=\dfrac{42}{28} = \dfrac{21}{14}= 1 \dfrac{1}{2}$

Answer 2

2/7 times 21/4= 42/28=6/4=3/2=1.5
