Answer 1

My suggestion is to go on cymath it would help u alot

Answer 2

We have been fractions and we are asked to simplify these fractions. Now let us start one by one.

1) $3 \frac{1}{2}+\frac{1}{8}$

Upon changing mix fraction into improper fraction we will get $\frac{7}{2}+\frac{1}{8}$

In order to simplify our fraction we need to make our denominators same. To make our denominators same we will multiply our first fraction by 4.

$\frac{7\cdot 4}{2\cdot 4}+\frac{1}{8}=\frac{28+1}{8}\\ =\frac{29}{8}$

Since are options are mixed fractions we have to convert our answer into mixed fraction.

$=\frac{29}{8}=3 \frac{5}{8}$

Option D is correct.

2) $2 \frac{3}{4}+5 \frac{3}{5}$

$\frac{11}{4}+\frac{28}{5}$

Now we will make both of our denominators same.

$2 \frac{3}{4}+5\frac{3}{5}\\ \\ \frac{5\cdot 11}{5\cdot 4}+\frac{4\cdot 28}{4\cdot 5}\\ \\ \frac{55}{20}+\frac{112}{20}$

$\frac{167}{20}\\ \\ 8 \frac{7}{20}$

Therefore, correct choice is option (C).

Hope you can use these concepts to answer the rest of the questions :)
