Question

Least common denominator of 1/5 and 4/15

Answer 1

Answer:

15

Step-by-step explanation:

you can't divide 4/15 down to have a denominator of 5 since 4 cant divide by 3 evenly

you can't divide 15 by something to get 10

so the only answer is 15

so 1/5 would turn into 3/15 by multiplying the top and bottom by 3

You have to work in factors of 5 because thats what they have in common

Answer 2

Answer:

15

Step-by-step explanation:

1/5+4/15=3/15+4/15

We have our common denominator.

We have to multiply the numerator with the denominator.

We multiplied 5 by 3 to get to 15, so we do the same to 1:

3/15+4/15=7/15
