Grade 4 Fractions: Unit Review

Worked examples

Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   3 × 1/2 = ?

   1. 3 × 1/2 means 3 groups of 1/2.
   2. Multiply the whole number by the numerator: 3 × 1 = 3. The denominator stays 2.
   3. So 3 × 1/2 = 3/2.

   Answer: 3/2

2. Example 2

   Write 0.8 as a fraction

   1. 0.8 has one digit after the decimal point, so it counts tenths.
   2. 0.8 is 8 tenths: the numerator is 8 and the denominator is 10.
   3. So 0.8 = 8/10.

   Answer: 8/10

3. Example 3

   1/2 ___ 1/10

   1. Both fractions have 1 piece, but the pieces are different sizes.
   2. More equal parts means smaller pieces: 1/2 is bigger than 1/10, so 1/2 is greater than 1/10.
   3. So 1/2 > 1/10.
