Question

b. Write an improper fraction using the LCM of
3 and 15 as the numerator.​

Answer 1

3 = 3 × 1

15 = 3 × 5

LCM = 3 × 5

= 15

The improper fraction will be

$14 \frac{1}{1}$

Answer 2

Answer:

15/12

Step-by-step explanation:

LCM of 3 and 15:

Multiples of 3 are 3, 6, 9, 12, 15,....

Multiples of 15 are 15, 30, 45, 60,....

Hence, LCM = 15

So, we take 15 as the numerator, and in order to make an improper fraction we need to make sure that the numerator is greater than the denominator. Here, we can take any number less than 15 (I have taken 12).

The required improper fraction is 15/12.
