Math Problem Statement

Division problems involving a four-digit number divided by a one- or two-digit number, with results rounded to two decimal places.

Solution

Let's go through and solve the division problems from the image, rounding each answer to two decimal places:

  1. 4510÷2=22554510 \div 2 = 2255
  2. 1559÷4=389.751559 \div 4 = 389.75
  3. 5892÷7=841.715892 \div 7 = 841.71
  4. 7512÷5=1502.47512 \div 5 = 1502.4
  5. 4175÷5=8354175 \div 5 = 835
  6. 8668÷5=1733.68668 \div 5 = 1733.6
  7. 5532÷14=395.145532 \div 14 = 395.14
  8. 6824÷23=296.76824 \div 23 = 296.7
  9. 8240÷17=484.718240 \div 17 = 484.71
  10. 4602÷15=306.84602 \div 15 = 306.8
  11. 6680÷13=513.856680 \div 13 = 513.85
  12. 5432÷27=201.195432 \div 27 = 201.19

Do you want details on any of these calculations or have any questions?

Here are 5 follow-up questions to test your understanding:

  1. What is the result of 5632÷165632 \div 16, rounded to two decimal places?
  2. How do you determine how many decimal places to round to in division problems?
  3. What happens when you divide a number by 1?
  4. Try dividing 7891 by 6 and rounding to two decimal places.
  5. Why is rounding important in real-world division problems?

Tip: When rounding to two decimal places, always look at the third decimal place to decide whether to round up or stay the same.
