The Comparing decimals 2 exercise used to appear under the 5th grade (U.S.) Math Mission, Arithmetic Math Mission and Pre-algebra Math Mission, but was apparently removed. This exercise practices use of the inequality symbol, in this case with decimals.

Types of Problems

There is one type of problem in this exercise:

  1. Compare the decimals: This problem provides two decimal numbers. It asks users to compare them by selecting the correct comparison symbol from among <, >, and =.
    Cd2-1

    Compare the numbers

Strategies

This exercise is medium to get accuracy badges because sometimes comparison in the decimals can be a little subtle if the user goes too quickly. Once users get their mind set, the speed badges are easy because it only takes one click.

  1. Try to find the first spot where numbers differ to ease the comparison attempt.

Real-life Applications

  1. Decimals appear in every-day media to display information to consumers.
  2. Decimals are very common in shopping. Price tags, food labels, and receipts all contain decimals.
  3. At gas pumps, decimals are used to show how much gas is pumped and much it costs per gallon.
