Question

What is the least common denominator of 3/5 and 2/15?​

Answer 1

15.

Explanation:

LCD: THE SMALLEST MULTIPLE TWO OR MORE DENOMINATORS HAVE IN COMMON.

An easy way to find the least common denominator (LCD), is by listing the multiples of the denominators and circling the smallest multiple that both denominators have in common.

SOLVE:

`5: 5, 10, 15, 20, 25, 30, 35, 40.`

`15, 15, 30, 45, 60, 75, 90, 105, 120.`

The smallest multiply both numbers have in common is 15.

I, Therefore, believe the LCD for 3/5 and 2/5 is 15.

Answer 2

15

hope this helps

have a good day :)

Explanation:

9/15 and 2/15 just

the mutiples of 5=5, 10, 15, 20

the multiples of 15=15, 30, 45, 60

so the common denominator is 15 so multiple 5 and 3 to get the denominator is 15 and the numerator of 9
