Answer 1

2.

Okay so like last time we'll start with converting them to improper fractions

1 1/2 = 3/2

2 1/3 = 7/3

Okay so the denominators are different

So what is the lowest multiple that 3 and 2 have in common?

It's 6!

So, we'll rewrite them.

2 x 3 = 6 so multiply the numerator by 3 also.

3 x 2 = 6, so multiply 7 by 2 as well. (Whatever is done to the denominator MUST be done to the numerator!)

So we have:

9/6 & 14/6.

we can clearly see by looking at the numerator that 14/6 is bigger. So subtract 9/6 from 14/6.

14 - 9 = 5

5/6

So,

The angelfish has grown 5/6 more inches.
