What you’ll learn
- Explain why equivalent fractions represent the same value.
- Read decimal places as tenths, hundredths, and smaller units.
- Use a representation that helps with the question in front of you.
Name the whole and the unit
A fraction describes a number of equal-sized parts. The denominator identifies the size of the fractional unit; the numerator counts those units. Comparing pictures only makes sense when they refer to the same whole.
Different notation, the same number
A fraction, decimal, or percentage can express the same quantity. For example, 3/4 and 0.75 are equal. Learning the connection is more useful than treating each notation as an unrelated set of rules.
Prepare for proportions and algebra
Equivalent values help with rates, percentages, measurements, and equations. These first skills focus on equivalence and decimals; a course may also require further work on fraction operations.
