Question

Estimate 10/12-3/8 using benchmarks values

Answer 1

To estimate \( \frac{10}{12} - \frac{3}{8} \) using benchmark values, we can first convert these fractions to simpler, easier-to-work-with approximations.

1. **Estimate \( \frac{10}{12} \)**: This fraction can be approximated to \( \frac{5}{6} \), which is close to \( 1 \) (as \( \frac{6}{6} = 1 \)).

2. **Estimate \( \frac{3}{8} \)**: This fraction is less than \( \frac{4}{8} = \frac{1}{2} \). Therefore, you can estimate it as \( \frac{1}{2} \).

Now, we can estimate the subtraction:

\[
\frac{10}{12} - \frac{3}{8} \approx 1 - \frac{1}{2} = \frac{1}{2}
\]

So, the estimated value of \( \frac{10}{12} - \frac{3}{8} \) using benchmark values is approximately \( \frac{1}{2} \).
