Answer 1

[AI-generated answer — Bot GPT 3.5]

This problem requires finding the least common multiple (LCM) of 9 and 12.

First, let's list the multiples of 9 and 12:

Multiples of 9: 9, 18, 27, 36, 45, ...

Multiples of 12: 12, 24, 36, 48, ...

The least common multiple (LCM) is the smallest number that is a multiple of both 9 and 12.

From the list, we see that 36 is the smallest number that appears in both lists. Therefore, it will take 36 weeks for Jiani and Rosa to get paid at the same time.

Answer 2

Add the following fractions: 215 + 13 (1 point)

To add fractions, we need a common denominator.

The denominator of the first fraction, 215, is 1 because it is a whole number.

The denominator of the second fraction, 13, is also 1 because it is a whole number.

Since the denominators are already the same, we can simply add the numerators:

215 + 13 = 228

So, the sum of the fractions 215 + 13 is 228.
