Answer
Explanation:
Step1: Convert decimals to integers
Multiply (4.08) by (100) to get (408), and multiply (5.3) by (10) to get (53). Now we need to multiply (408\times53). [408\times53=(400 + 8)\times53]
Step2: Use distributive property
[ \begin{align*} (400 + 8)\times53&=400\times53+8\times53\ &=21200+424\ &=21624 \end{align*} ]
Step3: Adjust for decimal places
We multiplied (4.08) by (100) and (5.3) by (10), so the total multiplier is (100\times10 = 1000). Now divide (21624) by (1000). [21624\div1000 = 21.624]
Answer:
(21.624)
