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

`(4)/(5) - (1)/(4)`

Find the least common denominator :

4 * 5 = 20

Adjust fractions based on the LCD


`(4*4)/(20) - (5)/(20)`



`(4*4-5)/(20)`


`(16-5)/(20)`


`= (11)/(20)`

hope this helps!
