Show answer & explanation
Correct answer: A
To determine the correct descending order for the expressions, we must first calculate the value of each:
Problem Analysis
Expression A: 35 ÷ 0.07
Calculation: 35 ÷ (7 / 100) = 35 × (100 / 7) = 5 × 100 = 500
Expression B: 2.5 ÷ 0.0005
Calculation: 2.5 ÷ (5 / 10000) = 2.5 × (10000 / 5) = 0.5 × 10000 = 5000
Expression C: 136.09 ÷ 43.9
Calculation: 136.09 ÷ 43.9 is approximately 3.1
Descending Order Solution
Comparing the simplified values:
5000 (B) > 500 (A) > 3.1 (C)
The correct descending order is B > A > C.
