Question

Work out 4/5 - 1/4 ???? Please can someone help?!

Answer 1

You need to find the common denominator, which is 20.
4/5=16/20
1/4=5/20
16/20-5/20=11/20
The answer is 11/20.

Answer 2

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

Find the least common denominator :

4 * 5  = 20

Adjust fractions based on the LCD

$\frac{4*4}{20} - \frac{5}{20}$


$\frac{4*4-5}{20}$

$\frac{16-5}{20}$

$= \frac{11}{20}$

hope this helps!
