Part B: Fill in the Blank
Write the correct answer on each line.
1. Emma paid $2.60 and Jake paid $2.06. The more expensive item cost $2.60.
$2.60 is more expensive because comparing the tenths place shows 6 tenths versus 0 tenths, so $2.60 is much greater than $2.06.
2. 5 dimes equal $0.50.
5 dimes equal $0.50 because each dime is worth $0.10, and 5 times $0.10 equals $0.50, or half a dollar.
3. Order from least to greatest: $1.50, $1.05, $1.55. Answer: $1.05, $1.50, $1.55.
$1.50 goes in the middle because $1.05 has the fewest tenths (0), $1.50 has 5 tenths, and $1.55 has 5 tenths plus 5 extra hundredths.
4. A snack costs 99 cents. Written as a dollar amount this is $0.99.
99 cents equals $0.99 because each cent is one hundredth of a dollar, so 99 cents is 99 hundredths, written as 0.99.
5. In $7.42, the value of the digit 4 is 4 tenths of a dollar.
The digit 4 is in the tenths place, so it represents 4 tenths of a dollar, which equals $0.40 or 40 cents.
