Question

Find the least common denominator between the two fractions. 1/4 and 3/5

Answer 1

To Find the least common denominator you have to find the multiples of each number

multiple means the product of each factor

so the multiples of 4 would be 4 8 12 16 20

you want to name at least five multiples but if there are not the same multiples you might have to list more

the multiples of 5 would be 5 10 15 20

then I can stop there because I have found two of the same multiples

so now we have our least common denominator which is 20

HOPE THIS HELPS!!!
