Estimate

10/12 − 3/8

using benchmark values. Your equation MUST show the estimate for each fraction and the final estimate for the expression. (Explain and estimate)

Step-by-step explanation:

Given expression:

To estimate the given expression using the benchmark values.

Solution:

We can plot the given expression in a number line.

From the number lines, we can see that,

is closest to 1. So, we can estimate the fraction as 1 which is the benchmark value for the fraction.

is closest to . So, we can estimate this fraction as which is the benchmark fraction.

So, the expression can be re-written as:

⇒   (Answer)

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!
