benchmark fractions, like 1/2
Benchmark fractions are commonly used fractions that help us estimate and compare the size of other fractions
Benchmark fractions are commonly used fractions that help us estimate and compare the size of other fractions. One of the most commonly used benchmark fractions is 1/2.
To understand benchmark fractions better, let’s look at their definition. A benchmark fraction is a fraction that is easy to visualize, remember, and work with. They are typically fractions that represent equal parts of a whole or fractions that have a clear representation in real-life objects or situations.
1/2 is a benchmark fraction because it represents half or 50% of something. It is easy to understand and visualize as splitting an object, shape, or quantity into two equal parts. For example, if you have a pie and you cut it into two equal pieces, each piece would represent 1/2 of the pie.
Benchmark fractions, like 1/2, are useful when comparing or estimating the size of other fractions. For instance, if you have a fraction like 3/8, you can use the benchmark fraction 1/2 as a reference point to estimate where it lies between 0 and 1. Since 1/2 is larger than 3/8, you can say that 3/8 is slightly less than half or closer to 0. You can also compare it with other benchmark fractions like 1/4 and 3/4 to further refine your estimate.
In summary, benchmark fractions like 1/2 are used as reference points to estimate and compare the size of other fractions. They represent commonly understood fractions that are easy to visualize and work with.
