Answer 1

Given: $\frac{3}{4} +\frac{2}{5}$

We have to add the above expression.

As we know that adding two or more numbers together is known as an addition.

Addition as denoted by(+).

Following are the properties of addition:

1. Identity property of zero.
2. Inverse property.
3. Commutative property.
4. Associative property.

We are solving in the following way:

We have,

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

First, we will make the denominator the same, and then we will simplify the equation.

As we know that the LCM of$4\ and\ 5\ is\ 20$.

Now,

$=>\frac{3}{4} \times\frac{5}{5} +\frac{2}{5} \times \frac{4}{4}\\\\=>\frac{15}{20} +\frac{8}{20} \\\\=>\frac{15+8}{20} \\\\=>\frac{23}{20}$

Hence, the solution of the above equation is$\frac{23}{20}$.
