Answer: No, it won't make Jackson tall enough to ride the roller coaster.
Explanation:
We need to make the conversion from mixed number to improper fraction:
- Multiply the whole number part by the denominator of the fraction.
- The sum of this product and the numerator of the fraction, will be the numerator of the improper fraction.
- The denominator does not change.
Then:

Jackson needs to be
inches taller to ride the rolles coaster.
The pair of boots add
inches to his height and the insole adds
inches to his height.
Then, we need to add these fractions in order to know if this will make him appear tall enough to ride the rooller coaster.
Since the denominator of these fractions are different, we must find the Least Common Denominator (LCD):

Finally, adding the fractions, we get:

To convert this result to mixed numbers:
- When we divide the numerator 31 by the denominator 24, we get a quotient of 1. This will be the whole number.
- We also get a remainder of 7. This will be the numerator of the fraction.
- The denominator doese not change.
Then:

Therefore, since
, the boots and the insole will not make Jackson appear tall enough to ride the roller coaster.
