The Finding percents exercise appears under the 6th grade (U.S.) Math Mission, Arithmetic essentials Math Mission, Pre-algebra Math Mission, Algebra basics Math Mission and Mathematics I Math Mission. This exercise introduces the basic percent equations (at least two of them).

Types of Problems

There are two types of problems in this exercise:

  1. Find what amount: This problem asks for the value of a percentage of a particular number. The user is asked to type the correct response in an answer box.
    Fp1

    Find what amount

  2. Find what percentage: This problem asks what percentage of some total is some value worth. The user is asked to enter the percentage in the provided space.
    Fp2

    Find what percentage

Strategies

This exercise is easy to get accuracy badges because both of the equation types are introduced at the beginning of experience with percentage equations. The and Speed badges are also easy because the equations easy to implement as soon as user realizes which one is being asked.

  1. On the first type, Find what amount, multiply the two number users see and divide by 100 (unless they convert the percentage to a decimal before multiplying).
  2. On the Find what percentage type users need to divide the first number they see by the second number and then multiply by 100 (unless they can move the decimal mentally).
  3. For the Find what percentage the problem is asking for the whole percentage (note the % sign in the question) so do not unnecessarily (and incorrectly) convert users answer to a decimal answer.

Real-life Applications

  1. Fractions, decimals, and percents are used in many sports such as basketball to determine how many field goals the player has made over how many they attempted.
