Question

pls answer me tis.
The q is in the picture​

Answer 1

Answer:

a) 57/(((10+5)-3*2)+10)

= 57/(15-3*2)+10)

= 57/9+10

= 57/19

= 3

b) 300/(375-(440-(150-60-50)))

= 300/(375-(440-40))

= 300/(375-400)

= 300/ -25

= -12

pls mark as brainliest

Answer 2

Answer:

Question -:

a) 57÷[{(10+5)-3×2}+10]

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\:\:\:\:\:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \:\:\:- - -$

b) 300÷[375-{440-(150-60-50)}]

Concept -:

After simplifying the question we have to find the answer .

And the line above the 60-50 . We have to find this first . So , if I will not give a line then also you think I have solve that first .

And used BODMAS formula to find the answer .

B = Brackets

O = Of

D = Division

M = Multiplication

A = Addition

S = Subtraction

Solution -:

(a) 57÷[{(10+5)-3×2}+10]

= 57÷[{15-3×2}+10]

= 57÷[{15-6}+10]

= 57÷[9+10]

= 57÷19

= 3

____________________________________

(b) 300÷[375-{440-(150-60-50)}]

(First , 60-50)

= 300÷[375-{440-(150-10)}]

= 300÷[375-{440-140}]

= 300÷[375-300]

= 300÷75

= 4

Answer -:

So , the answer of (a) is 3 .

And the answer of (b) is 4 .
