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:
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
