0.07 × 0.28 ÷ 0.04 + 0.64 - 1.64 ÷ 0.04

Question

Simplify the expression:

0.07 × 0.28 ÷ 0.04 + 0.64 - 1.64 ÷ 0.04

Accepted Answer

Step 1: Calculate 0.07 × 0.28 = 0.0196

Step 2: Divide the result by 0.04: 0.0196 ÷ 0.04 = 0.49

Step 3: Calculate 1.64 ÷ 0.04 = 41

Step 4: Now substitute these values back into the expression:  
0.49 + 0.64 - 41

Step 5: Add 0.49 and 0.64: 0.49 + 0.64 = 1.13

Step 6: Subtract 41 from 1.13: 1.13 - 41 = -39.87

The correct answer is -39.87, which corresponds to option 2.
