Question

divide. 12.4 ÷ 3.2

Explanation:

Step1: Convert decimals to integers

Multiply both the dividend and the divisor by 10 to eliminate the decimal points: \(12.4\times10 = 124\), \(3.2\times10 = 32\). So the problem becomes \(124\div32\).

Step2: Perform the division

Divide 124 by 32. \(32\times3 = 96\), \(124 - 96 = 28\). Bring down a zero (we can think of 124 as 124.00... for decimal division) to get 280. \(32\times8 = 256\), \(280 - 256 = 24\). Bring down another zero to get 240. \(32\times7 = 224\), \(240 - 224 = 16\). Bring down another zero to get 160. \(32\times5 = 160\). So putting it all together, \(124\div32 = 3.875\).

Answer:

\(3.875\)
