what is the least common denominator of 4/5ths and 5/7ths

Sagot :

Answer:

35 is the least common denominator

Step-by-step explanation:

35 is the least (smallest) common (same) multiple of 5 and 7. We use the smallest number that both 5 and 7 go into, because its supposed to be easier to use smaller numbers.

4/5 becomes 28/35 and 5/7 becomes 25/35. And now that they have the same denominator, you could add or subtract them.
