Question

25−12÷[(8−5)×1] help me with this

Answer 1

Given Equation:-

$\sf25 - 12 \div [(8 - 5) \times 1]$

Step-by-step explanation:-

$\dashrightarrow \sf25 - 12 \div [(8 - 5) \times 1]$

first write the equation so that you'll emit minor mistakes of writing wrong digits.

$\dashrightarrow \sf25 - 12 \div [(3) \times 1]$

subtract 8 and 5 , which will give us result as 3

$\dashrightarrow \sf25 - 12 \div [3 \times 1]$

open the brakets that contains 3.

$\dashrightarrow \sf25 - 12 \div [3]$

multiply 3 with 1 which will result 3.

$\dashrightarrow \sf25 - 12 \div 3$

open the brakets of 3.

$\dashrightarrow \sf25 - \dfrac{12}{3}$

to make it easy to understand I have converted it into fraction form.

$\dashrightarrow \sf25 - \dfrac{2 \times 2 \times 3}{3}$

simplify 12 which is contained in numerator.

$\dashrightarrow \sf25 - \dfrac{2 \times 2 \times \cancel3}{\cancel3}$

as we can see after converting into fraction 3 is common both in numerator and denominator. So cancel ir.

$\dashrightarrow \sf25 - (2 \times 2)$

we no longer need the fraction as 3 is canceled.

$\dashrightarrow \sf25 -4$

multiply 2 with 2 which will result 4.

$\dashrightarrow \bf21$

finally after subtracting 25 and 4 , we got our answer as 21.

Rule applied:-

B : bracket

O : on/off

D: divide

M : multiply

A : add

S : subtract

Answer 2

The value of the expression is 21 :)
