OPTION 1: convert them to decimals and them find a numebr between them
---> 1/4=0.25
---> 3/5=0.6
now 0.6-0.25 = 0.35 = 35/100 = 7/20

OPTION 2: make both of their denominators equal(to do this, multiply and divide one fraction with the denominator of the second)
---> 1/4 * 5/5
= 5/20
---> 3/5 * 4/4
= 12/20

now the fractions between 5/20 and 12/20 are 6/20, 7/20, 8/20, 9/20, 10/20, 11/20 and more..!!

hope this helped =)

4 = 2 x 2
5 = 5

The LCM of 4,5 is:
2 x 2 x 5
= 20

1/4 = 5/20
3/5 = 12/20

Fractions between 1/4 and 3/5 are:
6/20 (3/10) , 7/20 , 8/20 (2/5) , 9/20 , 10/20 (1/2) , 11/20

You have to convert the fractions from 1/4 to 5/20 and 3/5 to 12/20. In between those fractions are multiple fractions. Like 6/20, 7/20, 8/20, 9/20, 10/20, and 11/20.

there's an infinite number of fractions between 1/4 and 3/5. an easy one is 4/9. the one halfway between is (1/4 + 3/5)/2 = (17/20)/2 = 17/40

it is (1/4 + 3/5) / 2 = 17 / 40
