Simplify:
1.17×{16-(17-2)}=
2.80-{(25-8)+(40-23)}=
3.(30÷6)÷{(6×12)÷8}=
4.{240÷{5(6+3-7)}+17×2+4}=

plese give the answers.​.​

Answer 1

Step-by-step explanation:

Given:-

1.17×{16-(17-2)}

2.80-{(25-8)+(40-23)}

3.(30÷6)÷{(6×12)÷8}

4.{240÷{5(6+3-7)}+17×2+4}

To find:-

Simplify the following expressions?

Solution:-

1) Given numerical expression is 17×{16-(17-2)}

=> 17× {16-(15)}

=> 17×{16-15}

=> 17×{1}

=> 17×1

=> 17

17×{16-(17-2)} = 17

2) Given numerical expression is

80-{(25-8)+(40-23)}

=> 80 - {(17)+(17)}

=> 80-{17+17}

=> 80-{34}

=> 80-34

=> 46

80-{(25-8)+(40-23)} = 46

3) Given numerical expression is .

(30÷6)÷{(6×12)÷8}

=> (5)÷{(72)÷8}

=> (5)÷{72÷8}

=> 5÷(9)

=> 5/9

(30÷6)÷{(6×12)÷8} = 5/9

4. Given numerical expression is

{240÷{5(6+3-7)}+17×2+4}

=>{240 ÷ {5(9-7)}+(34+4)}

=> {240÷{5(2)}+38}

=> {240÷{10+38}

=> 240÷48

=> 240/48

=> 5

{240÷{5(6+3-7)}+17×2+4} = 5

Answer:-

1 .17×{16-(17-2)} = 17

2.80-{(25-8)+(40-23)} = 46

3.(30÷6)÷{(6×12)÷8} = 5/9

4.{240÷{5(6+3-7)}+17×2+4} = 5

Used formula:-

BODMAS rule:

• B= Brackets

• O = Of

• D = Division

• M = Multiplication

• A= Addition.

• S = Subtraction
