Q.

3

ones

2

te ths =? Hundreths

Understand place value: First, let's understand the place value of the given numbers. We have $3$ ones and $2$ tenths. We need to convert this into hundredths.
Convert ones to hundredths: To convert ones to hundredths, we multiply by $100$ because there are $100$ hundredths in one whole. $\newline$ So, $3$ ones is $3 \times 100$ hundredths. $\newline$ $3 \times 100 = 300$ hundredths.
Convert tenths to hundredths: To convert tenths to hundredths, we multiply by $10$ because there are $10$ hundredths in one tenth. $\newline$ So, $2$ tenths is $2 \times 10$ hundredths. $\newline$ $2 \times 10 = 20$ hundredths.
Add hundredths together: Now, we add the hundredths from the ones and the tenths together to get the total number of hundredths. $300$ hundredths (from the ones) + $20$ hundredths (from the tenths) = $320$ hundredths.
