Question

1. 40.32 ÷ 4.8

Explanation:

Step1: Convert divisor to integer

Multiply both dividend and divisor by 10 to eliminate the decimal in the divisor: \(40.32\times10 = 403.2\), \(4.8\times10 = 48\). Now the problem becomes \(403.2\div48\).

Step2: Perform long division

Divide 403.2 by 48. 48×8 = 384, subtract 384 from 403.2 to get 19.2. 48×0.4 = 19.2. So total is 8 + 0.4 = 8.4.

Answer:

\(8.4\)
