Given:

2.85 cm long

Determine the mixed number that represents the length.

Solution:

In order to determine the mixed number that represents the length, we must exclude first the whole number and focus on the decimal. .85 contains two decimal places to the right with a final place value of hundredths, therefore we can determine its fraction by making .85 a whole number, and dividing it by 100 based from its place value.

= 85/100

Convert to lowest terms by dividing 5.

= 17/20

Now that we have the fraction, we can simply put the whole number 2 in front.

= 2 17/20

Final answer:

2 17/20
