What is the best estimate of the sum of the fractions?

Mathematics

hoa [83]3 years ago
8 0

Answer:

14 1/2

Step-by-step explanation:

Estimations only help us do some rough calculations. They don't give us correct answer but, again, they aren't supposed to.

When estimating sum of the fractions, we should estimate each fraction separately and then just add those estimations up.

For example, 31/4 is somewhere just below 8, but we'll estimate it to 8. Similarly, 17/3, is a bit less then 6, but close enough to be rounded up.

Finally, 8/18 is somewhere near 1/2, so we round it up to that value.

Now, we simply add up all these estimations:

8+6+1/2 = 14 1/2
