Skill: Identify fractions greater than one

Explanation and Free Practice Resources

A positive fraction is greater than one when it represents more than one whole: in ab\frac{a}{b}, the numerator counts more equal parts than the denominator requires for one whole (a>ba>b); a=ba=b represents exactly one. Area models and number lines show such fractions extending beyond 1, and they may be written as an improper fraction or a whole number plus a fraction. Operations and more advanced fraction comparisons are not included.

Detailed Explanation: Identify fractions greater than one

A fraction is greater than 1 when it shows more than one whole.

In ab\frac{a}{b}:

  • The denominator bb tells how many equal parts make one whole.
  • The numerator aa tells how many parts there are.
  • If the numerator is greater than the denominator, then the fraction is greater than 11.

Example: Is 74\frac{7}{4} greater than 1?

  1. The denominator is 44, so 4 fourths make 1 whole:
44=1\frac{4}{4}=1
  1. The numerator is 77, so 74\frac{7}{4} means 7 fourths.

  2. Since 7>47>4, there are enough fourths to make one whole, with extra fourths left over.

Therefore,

74>1\frac{7}{4}>1

You can picture 74\frac{7}{4} as 1 whole and 3 more fourths:

74=134\frac{7}{4}=1\frac{3}{4}

Remember: compare the numerator and denominator. If the numerator is larger, the positive fraction is greater than 1.
