Answer 1

Answer:

13/4+(96-17/9)

=13/4+71/9

=117+284/36

=401/36

Answer 2

To simplify :$1\frac{3}{4} + 3\frac{2}{3} - 1\frac{7}{9}$  

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 $1\frac{3}{4} + 3\frac{2}{3} - 1\frac{7}{9}$  

          $= \frac{7}{4} + \frac{11}{3} - \frac{16}{9}$  

• Taking LCM we equalize denominator.
• LCM = 36

           $\frac{63 + 132 - 64}{36} \\= \frac{131}{36}$

Hence , on simplification we get , $\frac{131}{36}$
