Which of the following expressions is equivalent to 2.3 ×5.01 ? Choose 1 answer: (A) 23 ×501 ×(1)/(10) (B) 23 ×501 ×(1)/(100) (c) 23 ×501 ×(1)/(1,000) (D) 23 ×501 ×(1)/(10,000)

Rewrite without decimal: Rewrite the expression without decimal. 2.3 can be written as 23 and 5.01 can be written as 501.Multiply whole numbers: Multiply the whole numbers. 23 × 501 = 11523Count decimal places: Count the decimal places in the original expression. 2.3 has one decimal place. 5.01 has two decimal places. 2.3 × 5.01 has 1 + 2 = 3 decimal places.Determine correct expression: Determine the correct expression with the decimal places. To have 3 decimal places in the product, we need to divide by 10^3 (which is 1000). So the equivalent expression is 23 × 501 × (1/1000).

\newline

Choose

1

answer:

\newline

(A)

23 \times 501 \times \frac{1}{10}

\newline

(B)

23 \times 501 \times \frac{1}{100}

\newline

(C)

23 \times 501 \times \frac{1}{1,000}

\newline

(D)

23 \times 501 \times \frac{1}{10,000}

Rewrite without decimal: Rewrite the expression without decimal. $2.3$ can be written as $23$ and $5.01$ can be written as $501$ .
Multiply whole numbers: Multiply the whole numbers. $\newline$ $23 \times 501 = 11523$
Count decimal places: Count the decimal places in the original expression. $\newline$ $2.3$ has $1$ decimal place. $\newline$ $5.01$ has $2$ decimal places. $\newline$ $2.3 \times 5.01$ has $1 + 2 = 3$ decimal places.
Determine correct expression: Determine the correct expression with the decimal places. $\newline$ To have $3$ decimal places in the product, we need to divide by $10^3$ (which is $1000$ ). $\newline$ So the equivalent expression is $23 \times 501 \times (1/1000)$ .
