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 contain 'Division' and 'Multiplication' are calculated,
Step-4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Given expression is,
⇒ (8.88 × 5.25) + 54.80 = ? × 4.19 + 27.897
We can write the given values as:
⇒ 8.88 ≈ 9 and 5.25 ≈ 5 and 54.80 ≈ 55
⇒ 4.19 ≈ 4 and 27.897 ≈ 28
Then,
⇒ (9 × 5) + 55 = ? × 4 + 28
⇒ 45 + 55 = ? × 4 + 28
⇒ 100 = ? × 4 + 28
⇒ 100 - 28 = ? × 4
⇒ 72 = ? × 4
⇒ ? = 72/4
