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.
