Write equivalent fractions for 3/4 and 3/5 using 20 as the common denominator

Answer 1

To find the equivalent fractions for 3/4 and 3/5 using a common denominator of 20, we need to determine the factors by which we need to multiply the numerators and denominators in order to obtain the new fractions.

For 3/4:
The denominator of 4 needs to be multiplied by 5 to become 20. Therefore, we also need to multiply the numerator of 3 by 5. This gives us:
(3/4) x (5/5) = 15/20

For 3/5:
The denominator of 5 needs to be multiplied by 4 to become 20. Therefore, we also need to multiply the numerator of 3 by 4. This gives us:
(3/5) x (4/4) = 12/20

Thus, the equivalent fractions for 3/4 and 3/5 when the common denominator is 20 are 15/20 and 12/20 respectively.
