Let’s look at the volume of prisms that have fractional measurements.
The following diagram shows how to use division and multiplication to solve find the volumes of rectangular prisms with fractional bases and heights.
Scroll down the page for the answer to the “Are you ready for more?” section.
1/2 · 2/3 = 1/3
1/2 · 2/3 · 3/4 = 1/4
Since we are progressively multiplying by a fraction that is less than 1, the value will get smaller each time and will get closer and closer to 0.
1/1 · 2/1 = 2
1/1 · 2/1 · 1/3 = 2/3
The value will get bigger or smaller each time depending on whether the next number to multiply is greater or less than 1.
