ACTIVITY: Fractions [LO 2.1.5]

4. Let us first revise.

Do you still remember?

A fraction is a part of a whole: 35numeratordenominator35numeratordenominator size 12{ { {3} over {5} } ~ { {"numerator"} over {"denominator"} } } {}

  • Join column A with the correct answer in column B:
Table 2
  A   B
a) the numerator is smaller than the denominator e.g. 4747 size 12{ { { size 8{4} } over { size 8{7} } } } {}   mixed numbers
       
b) the numerator is bigger than the denominator e.g. 9292 size 12{ { { size 8{9} } over { size 8{2} } } } {}   proper fractions
       
c) natural numbers plus a common fraction e.g. 134134 size 12{1 { { size 8{3} } over { size 8{4} } } } {}   improper fractions
