Answer» Follow BODMAS rule to solve this question, as per the order given below, Step-1- PARTS of an equation enclosed in 'Brackets' must be SOLVED first and in the bracket, Step-2- Any mathematical 'Of' or 'Exponent' must be solved next, Step-3- Next, the parts of the equation that contains 'Division' and 'Multiplication' are calculated, Step-4- Last but not LEAST, the parts of the equation that contains 'Addition' and 'Subtraction' should be calculated. Given expression is, (360.97 ÷ 19) × 99.98 – (288.97 ÷ 17) × 99.98 = ? We can write the given values as: 360.97 ≈ 361, 99.98 ≈ 100, 288.97 ≈ 289 Approximating values in the given expression: ⇒ (361 ÷ 19) × 100 – (289 ÷ 17) × 100 = ? ⇒ 19 × 100 – 17 × 100 = ? ∴ ? = 100(19 – 17) = 200

Answer»

Follow BODMAS rule to solve this question, as per the order given below,

Step-1- PARTS of an equation enclosed in 'Brackets' must be SOLVED first and in the bracket,

Step-2- Any mathematical 'Of' or 'Exponent' must be solved next,

Step-3- Next, the parts of the equation that contains 'Division' and 'Multiplication' are calculated,

Step-4- Last but not LEAST, the parts of the equation that contains 'Addition' and 'Subtraction' should be calculated.

Given expression is,

(360.97 ÷ 19) × 99.98 – (288.97 ÷ 17) × 99.98 = ?

We can write the given values as:

360.97 ≈ 361, 99.98 ≈ 100, 288.97 ≈ 289

Approximating values in the given expression:

⇒ (361 ÷ 19) × 100 – (289 ÷ 17) × 100 = ?

⇒ 19 × 100 – 17 × 100 = ?

∴ ? = 100(19 – 17) = 200
