14/5 145 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:

7/10 \div 1/4 710÷14

CHANGE the operation symbol:

7/10 * 1/4 710⋅14

FLIP the second fraction:

7/10 * 4/1 710⋅41

Now multiply the fractions as you would normally.

7/10 * 4/1710⋅41

= (7 * 4)/(10 * 1) =7⋅410⋅1

= 28/10 =2810

= 14/5 =145

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