Question

25−12÷[(8−5)×1] help me with this

Answer 1

The value of the expression is 21 :)

Answer 2

Given Equation:-

`\sf25 - 12 / [(8 - 5) * 1]`

`\\ \\`

Step-by-step explanation:-

`\\`

`\dashrightarrow \sf25 - 12 / [(8 - 5) * 1]`

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

`\\`

`\dashrightarrow \sf25 - 12 / [(3) * 1]`

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

`\\`

`\dashrightarrow \sf25 - 12 / [3 * 1]`

open the brakets that contains 3.

`\\`

`\dashrightarrow \sf25 - 12 / [3]`

multiply 3 with 1 which will result 3.

`\\`

`\dashrightarrow \sf25 - 12 / 3`

open the brakets of 3.

`\\`

`\dashrightarrow \sf25 - (12)/(3)`

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

`\\`

`\dashrightarrow \sf25 - (2 * 2 * 3)/(3)`

simplify 12 which is contained in numerator.

`\\`

`\dashrightarrow \sf25 - (2 * 2 * \cancel3)/(\cancel3)`

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

`\\`

`\dashrightarrow \sf25 - (2 * 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.

`\\`
