Amanda [17]

Answer:

\frac{3}{8}\ mile

Step-by-step explanation:

-Amy walks a distance of 7/8 mile

-Tom walks a distance of 4/8 mile.

#We immediately notice that Amy has walked a longer distance than Tom.

We subtract Tom's distance from Amy's to find how much further Amy walked;

\bigtriangleup d=d_A-d_T\\\\=\frac{7}{8}-\frac{4}{8}\\\\=\frac{3}{8} mile

Hence, Amy has walked 3/8 miles further than Tom has.

nasty-shy [4]

Answer:

44

Step-by-step explanation:

Let x and y be the total number of questions in part 1 and part 2 exams respectively.

For part 1:

Number of correct question = 4/5 of the total number of question in part 1

\Rightarrow 16=\frac{4}{5}\times x

\Rightarrow x=20

For part 2:

Number of corrected question = 2/3 of total number of question in part 2

\Rightarrow 16=\frac{2}{3}\times x

\Rightarrow x=24

So, the total umbers of the questions on Stephanie's exam

=x+y

=20+24

=44

Hence, the total umbers of the questions on Stephanie's exam was 44.
