Answer:
No, it's not
Step-by-step explanation:
Lets simplify the two fractions to the lowest term
for 5/20 we'll divide the numerator and denominator by 5 (the HCF of the two)
it then becomes 1/4
For 4/12 we'll divide the numerator and denominator by 4 (the HCF of the two)
it then becomes 1/3
1/4 = 0.25
1/3 = 0.33
therefore 5/20 is not equal to 4/12
