Answer 2

The answer is <em />$18\frac{3}{4}ft$

Since we have like denominators, we are able to add without any problem.

$10 \frac{1}{4} +8 \frac{2}{4}$...........................................Add the whole numbers first

$18 \frac{1}{4} + \frac{2}{4}$.............................................Add the fractions together

$18\frac{3}{4}$....................................................Remember to not add denominators together, but only the numerators (top numbers)

Thank you for your question! I hope this helped! :D Have an amazing day! :)
