$\frac{14}{5}$ $14/5$ or $2.8$ $2.8$

Explanation:

When dividing two fractions, an easy way to remember what to do would be the acronym KCF (Keep Change Flip).

KEEP the first fraction as is:

$\frac{7}{10} \div \frac{1}{4}$ $7/10 \div 1/4$

CHANGE the operation symbol:

$\frac{7}{10} \cdot \frac{1}{4}$ $7/10 * 1/4$

FLIP the second fraction:

$\frac{7}{10} \cdot \frac{4}{1}$ $7/10 * 4/1$

Now multiply the fractions as you would normally.

$\frac{7}{10} \cdot \frac{4}{1}$ $7/10 * 4/1$

$= \frac{7 \cdot 4}{10 \cdot 1}$ $= (7 * 4)/(10 * 1)$

$= \frac{28}{10}$ $= 28/10$

$= \frac{14}{5}$ $= 14/5$

If you want the fraction in decimal form, the answer would be $2.8$ $2.8$ .
