Question

Solve:

$7/10+2/5+3/2$

Answer 1

Given:

$7/10+2/5+3/2$

To add two unlike fractions, first change them to the like fractions.

Find the LCM of the denominator

LCM of $(10,5,2)=10$

Now, let us change each of the given fraction into an equivalent fraction having $10$ as the denominator.

$$\begin{gathered} \Rightarrow \left[\right(7/10)\times (1/1\left)\right]=(7/10) \\ \Rightarrow \left[\right(2/5)\times (2/2\left)\right]=(4/10) \\ \Rightarrow \left[\right(3/2)\times (5/5\left)\right]=(15/10) \end{gathered}$$

Now,

$$\begin{gathered} \Rightarrow (7/10)+(4/10)+(15/10) \\ \Rightarrow \left[\right(7+4+15)/10] \\ \Rightarrow (26/10) \\ \Rightarrow (13/5) \\ =2.6 \end{gathered}$$

Hence, the required solution is $\frac{13}{5}$
