Answer 3

To find the least common multiple (LCM) of the fractions 13/18, 3/8, and 1/36, we need to first convert them to a common denominator and then find the LCM of the resulting denominators.

The denominators of the fractions are 18, 8, and 36. To find the least common multiple of these numbers, we can list their multiples and find the smallest common multiple:

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, ... Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ... Multiples of 36: 36, 72, 108, 144, 180, ...

From the lists above, we can see that the smallest common multiple is 72.

Now, let's express each fraction with a denominator of 72:

13/18 = (13/18) * (4/4) = 52/72 3/8 = (3/8) * (9/9) = 27/72 1/36 = (1/36) * (2/2) = 2/72

The fractions are now 52/72, 27/72, and 2/72.

The LCM of the fractions is the LCM of the denominators, which is 72.

Therefore, the answer is 72.
