Question

Simplify the following:  
21 − 4.9 ÷ 7 + 3.9 × 0.4 + 0.9

Accepted Answer

Let's simplify the expression step by step using the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction):

Given: 21 − 4.9 ÷ 7 + 3.9 × 0.4 + 0.9

Step 1: Division and Multiplication first.
- 4.9 ÷ 7 = 0.7
- 3.9 × 0.4 = 1.56

So, the expression becomes:
21 − 0.7 + 1.56 + 0.9

Step 2: Addition and Subtraction from left to right.
- 21 − 0.7 = 20.3
- 20.3 + 1.56 = 21.86
- 21.86 + 0.9 = 22.76

Final Answer: 22.76
