Question

Yesterday annie walked 9tenth mile to her friends house they walk 1/3 mile to the library which is the best estimate for how far annie walked

Answer 1

This could be an adding fractions problem. We can add the two fractions together and then determine how many miles she walked.

 9       1
--- + ----
10     3

First, we need to find a common denominator. It would be 30, since this is the smallest number both 3 and 10 go into.

So, after that, we need to multiply each numerator by the number we needed to multiply our denominator by to get to 30.

So, 10 times 3 equals 30. So, we need to multiply 9 by 3 as well, which is 27.

Our new fraction here would be:

27
----
30

Next, to get 30, we need to multiply 3 by 10 to get 30. So, we also need to multiply 1 by 10, which is 10. 

Our new fraction would be:

10
---
30

So lets take a look at our new equation.

27   10
--- + ---- 
30   30

Lets add them together. Remember the denominators need to stay the same:

37
----
30

Now that we have an improper fraction, we need to simplify it. 37 goes into 30 once, and we have 7 left over.

So, our final answer would be:

1 and 7
         ----  of a mile.
          30
