A5.45
B6.35
C5.35
D4.35
Answer & Solution
Correct answer: C. 5.35
1. Write 20 as 20.00 so both numbers have two decimal places.
2. Subtract the hundredths: 0 - 5 cannot be done directly, so borrow, making it 10 - 5 = 5.
3. Subtract the tenths: with 1 borrowed, 9 - 6 = 3.
4. Subtract the ones and tens: 19 - 14 = 5.
5. Putting the columns together gives 5.35.
