Question

23×43÷670(55÷77)×76+98=6489÷85

Answer 1

Answer:

Two expressions are not equal

Step-by-step explanation:

We are given two mathematical expressions and we need to see if both equate or not.

First expression is

23 × 43 ÷ 670 (55÷77) × 76 + 98

Using DMAS rule to solve step by step;

= 23 × 43 ÷ 670 (0.714) × 76 + 98

= 23 × 43 ÷478.4 × 76 + 98

= 23 x 0.09  × 76 + 98

= 161.4 + 98

= 259.4

Now taking the second expressions

= 6489÷85

= 76.34

Two expressions are not equal

Answer 2

Given:

23×43÷670(55÷77)×76+98=6489÷85

To verify:

The given expression is correct or not.

Solution:

1) To verify we will solve the  expression side by side by the rule of the BODMAS

Let us take the LHS

• 23 × 43 ÷ 670 (55÷77) × 76 + 98

• 23 × 43 ÷ 670 (0.714) × 76 + 98

• 23 × 43 ÷478.4 × 76 + 98

• 23 x 0.09  × 76 + 98

• 157.32 + 98

• 255.32

2) Now take the RHS of the expression:

• 6489÷85

• 76.34

LHS ≠ RHS
