Answer 2

Given:

1). $2\frac{3}{4}$ ÷ ($1\frac{1}{2} - \frac{2}{5}$)

2). $(3.5\:\dot\:\frac{2}{7} - \frac{2}{3} )$ ÷ $16$

3). $5\frac{2}{5}$ - 4 ÷ $1\frac{2}{3}$

To find:

Simplify

Solution:

We will solve each of the given problems according to the rule of VBODMAS.

(1). $2\frac{3}{4}$ ÷ ($1\frac{1}{2} - \frac{2}{5}$)

= $\frac{11}{4}$ ÷ ( $\frac{3}{2} - \frac{2}{5}$ )

= $\frac{11}{4}$ ÷ ( $\frac{15 - 4}{10}$ )

= $\frac{11}{4}$ ÷  $\frac{11}{10}$

= $\frac{11}{4} \:\times\:\frac{10}{11}$

= $\frac{10}{4}$

= $\bold{\frac{5}{2}}$

(2). $(3.5\:\dot\:\frac{2}{7} - \frac{2}{3} )$ ÷ $16$

substituting 3.5 = $\frac{7}{2}$

= $(\frac{7}{2} \:\dot\:\frac{2}{7} - \frac{2}{3} )$ ÷ $16$

= $(1 - \frac{2}{3} )$ ÷ $16$

= $(\frac{3 -2}{3} )$ ÷ $16$

= $\frac{1}{3}$ ÷ $16$

= $\frac{1}{3} \:\times\:\frac{1}{16}$

= $\bold{\frac{1}{48}}$

(3).  $5\frac{2}{5}$ - 4 ÷ $1\frac{2}{3}$

= $5\frac{2}{5}$  ÷ $1\frac{2}{3}$ - 4

= $\frac{27}{5}$ ÷ $\frac{5}{3}$ - 4

= $\frac{27}{5} \:\times\:\frac{3}{5}$ - 4

= $\frac{81}{25}$ - 4

= $\frac{81 - 100}{25}$

= $\bold{\frac{-19}{25}}$
