Question

add altogether 7 1/2, 5 and 8 1/2​

Answer 1

Answer:

21 or 42/2

Step-by-step explanation:

First, make all the mixed fractions into improper fractions. So you will get $\frac{15}{2} \text{ and } \frac{17}{2}.$ Then make the fractions like fractions. You get : $\frac{15}{2},\frac{10}{2}, \frac{17}{2}$.

Add them, and you get $\frac{15 + 10 + 17}{2} = \frac{42}{2} = 21$
