Question

2 find the product 55.5 × 0.08 =

Explanation:

Step1: Multiply the numbers as integers

First, ignore the decimal points and multiply 555 (we can think of 55.5 as 555 tenths for easier calculation later, but here we just multiply 55.5 and 0.08 as if they were 555 and 8, then adjust for decimals) and 8. Wait, actually, 55.5 × 0.08. Let's do 55.5 × 0.08. We can write 55.5 as $\frac{555}{10}$ and 0.08 as $\frac{8}{100}$. Then multiply the numerators: 555 × 8 = 4440. Multiply the denominators: 10 × 100 = 1000. Then $\frac{4440}{1000}$ = 4.44. Alternatively, do decimal multiplication: 55.5 × 0.08. The number of decimal places in 55.5 is 1, in 0.08 is 2, so total decimal places is 3. Multiply 555 × 8 = 4440. Then move the decimal point 3 places to the left: 4.440, which is 4.44.

Step2: Verify the calculation

55.5 × 0.08. Let's do 55 × 0.08 = 4.4 and 0.5 × 0.08 = 0.04. Then add them together: 4.4 + 0.04 = 4.44. Yep, that matches.

Answer:

4.44
