Answer 2

This question can be solve by using BODMAS rule. BODMAS refers to

B = bracket

O = of

D = Division

M = Multiplication

A = Addition

S = Subtraction

Now coming towards the question

5×7 (7÷8)7÷5×5+4-5×5

So first we have to remove bracket

$5×7( 7 \times \frac{1}{8} )7 \div 5 \times 5 + 4 - 5 \times 5$

After removing bracket we will solve for division.

$\longrightarrow \: 5 \times 7 \times 7 \times \frac{1}{8} \times 7 \times \frac{1}{5} \times 5 + 4 - 5 \times 5$

The numbers which can be cancelled we will cancel them

$\longrightarrow \: 5 \times 7 \times 7 \times \frac{1}{8} \times 7 \times \frac{1}{ \cancel{5}} \times { \cancel{5 }}+ 4 - 5 \times 5$

After cancelling the numbers multiply the multiplicative term

$245 \times \frac{1}{8} \times 7 + 4 - 5 \times 5$

$\longrightarrow \: 245 \times \frac{7}{8} + 4 - 25$

$\longrightarrow \: \dfrac{1715}{8} + 4 - 25$

LCM of 8, 1 and 1 is 8

$\therefore \: \dfrac{1715}{8} + \dfrac{4 \times 8}{1 \times 8} - \dfrac{25 \times 8}{1 \times 8}$

$\longrightarrow \: \dfrac{1715 + 32 - 200}{8}$

According to the rule we have to first add and then subtract

$\longrightarrow \: \dfrac{1747 - 200}{8}$

$\longrightarrow \: \bold{ \dfrac{1547}{8} }$
