Question

first, represent the decimal using place value.
$7 \times 0.3 = $
$7 \times 3$ ones
$\checkmark 7 \times 3$ ones
$7 \times 3$ tenths
$7 \times 3$ hundredths

Explanation:

Step1: Recall place value of 0.3

The decimal 0.3 can be written as 3 tenths, because the first digit after the decimal point represents tenths place. So \( 0.3=\frac{3}{10} \), which is 3 tenths.

Step2: Analyze \( 7\times0.3 \)

So \( 7\times0.3 \) is the same as \( 7\times3 \) tenths. The option "7 × 3 ones" would be for \( 7\times3 \) (since 3 ones is 3), and "7 × 3 hundredths" would be for \( 7\times0.03 \) (since 3 hundredths is 0.03), so the correct representation is \( 7\times3 \) tenths.

Answer:

7 × 3 tenths
