Activity: fractions [lo 2.1.5]

4. Let us first revise.

Do you still remember?

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

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

5. Look at the following figures and then complete the table:
