🔢 Step-by-Step Solution

Step 1: Evaluate Multiplication and Division

Perform the multiplication and division operations first according to BODMAS: $4.5 imes 2.4 = 10.8$ , $\frac{12.8}{4} = 3.2$ , and $3.15 imes 2 = 6.3$ .

4.5imes2.4=10.8,12.84=3.2,3.15imes2=6.34.5 imes 2.4 = 10.8, \quad \frac{12.8}{4} = 3.2, \quad 3.15 imes 2 = 6.34.5imes2.4=10.8,412.8​=3.2,3.15imes2=6.3

Step 2: Perform Addition and Subtraction

Substitute the results back into the expression: $10.8 - 3.2 + 6.3$ . Grouping positive terms gives $10.8 + 6.3 = 17.1$ , and $17.1 - 3.2 = 13.9$ .

10.8−3.2+6.3=13.910.8 - 3.2 + 6.3 = 13.910.8−3.2+6.3=13.9

✅

A is correct because $4.5 imes 2.4 - 12.8 / 4 + 3.15 imes 2 = 10.8 - 3.2 + 6.3 = 13.9$ .
