Question

Find the sum: - 8/7-13/14 +7/3​

Answer 1

In context to questions asked,

We have to determine the value of expression.

So, as per questions,

It is given that,

$8/7-13/14 +7/3$

So, for determining the value of expression we will use fractional sum method

So, first we will take LCM of denominator and then solve the expression.

Thus we will get

$8/7-13/14 +7/3 \\ = > \frac{(8 \times 6) - (13 \times 3) + (7 \times 14)}{42} \\ = > \frac{48 - 39 + 98}{42} \\ = > \frac{107}{42}$

Hence, we will get 107/42 by solving the given expression.

Answer 2

To find : $\frac{8}{7} - \frac{13}{14} +\frac{7}{3}$

Solution :

• To solve the above equation we will follow BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

• where,  

       $\begin{array}{l} \\B= brackets\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { Division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

• According to above rule we will solve.
• $\frac{8}{7} - \frac{13}{14} +\frac{7}{3}$  

         $= \frac{48-39+ 98}{42} \\= \frac{107}{42}$

Hence , on solving above expression we get answer as $\frac{107}{42}$ .
