Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

To estimate the sum or difference of 8/9 + 4/7 it should be 1 1/2

It is also a way to find an approximate answer to a solution. To estimate products and quotients of mixed numbers, round the fractions to the nearest whole number. If the fraction is less than 12 round down and if it is more than 12 round up. First, since 411 is less than 12,8411 rounds down to 8.

Answer

the estimated sum is 11.59

And the estimated difference is

0.32

Step-by-step explanation:

The question bothers to know how well you understand your fraction

In a step by step approach we will estimate both the sum and the difference

Step one

Let us know what the sum is

8/9+4/7

The Lcm can be gotten by multiplying the denominators

9x7=63

56+36/63= 92/63

=11.59

Hence the estimated sum is 11.59

Step two

Let us estimate the difference also we have

8/9-4/7

Like before our Lcm =63

56-36/63=20/63

=0.32

Our estimated difference is 0.32
