Organize Decimals and Fractions: Sorting Numbers Above and Below 60%

Question

Organise the following into two groups of parts greater than 60% and parts less than 60%:

0.7,67100,59100,0.2,45 0.7,\frac{67}{100},\frac{59}{100},0.2,\frac{4}{5}

Video Solution

Step-by-Step Solution

To categorize the numbers based on being greater than or less than 60%, we will first convert the fractions into decimals:

  • 0.70.7 is already a decimal, equivalent to 70%70\%, which is greater than 60%60\%.
  • 67100=0.67 \frac{67}{100} = 0.67, equivalent to 67%67\%, which is greater than 60%60\%.
  • 59100=0.59 \frac{59}{100} = 0.59, equivalent to 59%59\%, which is less than 60%60\%.
  • 0.20.2 is already a decimal, equivalent to 20%20\%, which is less than 60%60\%.
  • 45=0.8 \frac{4}{5} = 0.8, equivalent to 80%80\%, which is greater than 60%60\%.

Based on these conversions and comparisons, we organize them into two groups:

The numbers less than 60%60\% are 0.20.2 and 59100\frac{59}{100}.

The numbers greater than 60%60\% are 0.70.7, 67100\frac{67}{100}, and 45\frac{4}{5}.

Rechecking our work against the answer choices given confirms that the correct grouping is choice 3. Therefore, the solution is as follows:

0.2,\frac{59}{100}<60\%

0.7,\frac{67}{100},\frac{4}{5}>60\%

Answer

0.2,\frac{59}{100}<60\%

0.7,\frac{67}{100},\frac{4}{5}>60\%
