Question

4/8 What is the closest benchmark number to 4/8?
a) 0.5
b) 1.0
c) 1.5
d) 2.0

Answer 1

The closest benchmark number to 4/8 is 0.5, which is option a) among the given answers.

Step-by-step explanation:

When asked what the closest benchmark number to 4/8 is, we are looking for the simplest or most commonly recognized number that closely represents the value of 4/8. Given the options a) 0.5, b) 1.0, c) 1.5, and d) 2.0, we must first recognize that 4/8 is equal to 0.5 when converted to a decimal. This makes option a) the closest benchmark number to 4/8. Benchmark numbers are commonly used reference points in mathematics that make estimating and comparing easier.

To show the student how to convert fractions to decimals, we can divide the numerator by the denominator. For 4/8, we divide 4 by 8 which gives us 0.5 as the decimal equivalent. Thus, the answer is clear:

1. 4/8 is equal to 0.5 in decimal form.
2. The benchmark number closest to 0.5 is indeed 0.5
3. Therefore, the correct answer is a) 0.5
