Question

find the sum of the following rational numbers solve any 2 on the number line 5/2+(-3/4)​

Answer 1

Answer:

$\frac{5}{2}+\frac{(-3)}{4}=\frac{7}{4}$

Step-by-step explanation:

The sum of two rational numbers is calculated as follow:

consider two rational numbers  $\frac{a}{b}$ and $\frac{c}{d}$

$\frac{a}{b}+\frac{c}{d}$

$=\frac{ad}{bd}+\frac{bc}{bd}$

$=\frac{ad+bc}{bd}$

Now,

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

$=\frac{2*5}{2*2}+\frac{(-3)}{4}$

$=\frac{10}{4}+\frac{(-3)}{4}$

$=\frac{10+(-3)}{4}$

$=\frac{7}{4}$
