Infinitely many ways!
Suppose you have the fraction 2/d.

<span>Pick </span>any<span> pair of integers a and b where b ≠ 0.</span>
Then 2b-ad is and integer, as is bd so that (2b - ad)/bd is a fraction.

Consider the fractions a/b and (2b - ad)/bd

<span>Their sum is </span>
a/b + (2b-ad)/bd = ad/bd + (2b-ad)/bd = 2b/bd = 2/d - as required.

<span>Since a and b were chosen arbitrarily, there are infinitely many possible answers to the question.</span>

Find the equivalent ratio for 64%. Write your answer in simplest form.

For this case we can do the following:

64% = 64/100

And if we simplify we got:

64/100 = 32/50 = 16/25 = 0.64

Answer:

65 miles

Step-by-step explanation:

There are two simultaneous equations . Remeber that v=d/t, 1hour = 60 minutes.

1. 40 = (d+15)/(t+0.5)

2. 50 = d/t

solving: d= 25 miles and t=0.5 hours.

The distance traveled is:

D=d+d+15

D=65 miles
