Yesterday, Annie walked 9/10 mile to her friends house. Together, they walked 1/3 mile to the library. Which is the best estimate for how far Annie walked yesterday?

Answers

Answer:

Total distance traveled by annie is $(37)/(30)$ mile.

Step-by-step explanation:

Distance covered by annie to her friend's house is

$(9)/(10)$ mile.

After there , annie and her friend travelled $(1)/(3)$ mile to the library.

We have to find the total distance covered by annie which can be find by adding total distance traveled by her,

Total distance traveled by annie = distance traveled to friend's house + distance traveled to library.

= $(9)/(10)+(1)/(3)$

Solving it further, we get

= $(27+10)/(30)$

= $(37)/(30)$

Thus, Total distance traveled by annie is $(37)/(30)$ mile.

0.9 + 0.333 = 1.233 miles
so about 1 1/2 miles or 1 1/4

so percent means parts out of 100 so
exg
10%=10/100=1/10

so 5 1/4% convert 1/4 to 0.25

5.25%=5.25/100=52.5/1000=525/10000
