Question

Please help me get the answers.

Answer 1

The answers are

1. $1$

2. $\frac{5}{8}$

3. $\frac{19}{5}$

What are fractions?

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. In ordinary English, a fraction refers to the number of parts of a specific size.

We are given,

1. $\frac{4}{7} + \frac{3}{7}$

As the denominator of both fractions are same we add the numerator

We get,

$\frac{7}{7}=1$

2. $\frac{7}{8}-\frac{2}{8}$

As the denominator of both the fractions are same we subtract the value in the numerator we get,

$\frac{7}{8}-\frac{2}{8}=$$\frac{5}{8}$

3. $6\frac{4}{5}-3$

We first simplify the first term of the equation,

$6\frac{4}{5}=\frac{34}{5}$

Now as the denominator is not same we use cross multiplication to perform the operation

$\frac{34}{5}-3=\frac{34-15}{5}$

On further simplifying we get,

$\frac{34-15}{5}=\frac{19}{5}$

Hence the answers are

1. 1

2. $\frac{5}{8}$

3. $\frac{19}{5}$
