    Find the quotient


This exercise is easy to get accuracy badges because users are dividing by pretty standard decimals. The speed badges can be done easily if they think of some of the decimals as fractions.

  1. A calculator goes against the spirit of the problem and is not likely to increase speed here.
  2. If users can think of the decimal as a fraction, many of these can turn into multiplication problems since dividing by a fraction is equivalent to multiplying by a reciprocal.
  3. Some of the standard fractions in decimal form: {0.2 \iff 5}, {0.25\iff 4}, {0.2\iff 5} and {0.1 \iff 10}.
  4. Dividing by 0.75 is like multiplying by {\frac{4}{3}}, so users can divide the number by 3, then divide by 4.

Real-life Applications

  1. Decimals appear in every-day media to display information to consumers.
