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

Burka [1]
If x is the number of people that come over to dinner, and y is how much ounces of broccoli he needs, then this is your equation:
7x = y is your answer

Because he needs 7 ounces for each person, to find the number of ounces he needs, you multiply 7 by the number of people.
