Estimate 10/12 -3/8 using benchmark values. Your mud equation must show the estimate for each fraction of the final estimate for the expression.
To estimate 10/12 - 3/8 using benchmark values, we can first simplify the fractions.
10/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. This gives us:
10/12 = 5/6
3/8 is already in its simplest form.
Now, let's estimate using benchmark values.
For the numerator, 5, the benchmark value closest to it is 6. So, we can estimate it as 6.
For the denominator, 6, the benchmark values closest to it are 4 and 10. Since 6 is closer to 4, we can estimate it as 4.
Thus, the estimated expression for 5/6 - 3/8 is approximately 6/4.
Let's calculate the estimate for each fraction:
Estimate for 5/6:
5/6 is approximately 6/4, which is 1 and 2/4.
Estimate for 3/8:
3/8 remains as it is.
Therefore, the final estimate for 10/12 - 3/8 is approximately 1 and 2/4 - 3/8.
