The fraction bar means "divided by." So finding the decimal equivalent of a fraction such as 1/4 means 1 divided by 4.
1 ÷ 4 = 0.25
It is not necessary to reduce a fraction before you convert it to a decimal but doing so might make the long division easier if you are doing it by hand.
For example, 9/12 = 9 ÷ 12 = 0.75. If you solve this with a calculator then it is easy to get the answer. However, if you use long division to solve this problem by hand or in your head, reducing 9/12 = 3/4, may make the problem easier. You may even recognize that 3/4 = 0.75 because 3 quarters equals 75 cents.

Answer:
x = 175 km
Step-by-step explanation:
We can use ratios to solve this problem.  Put the map distance over the real life distance.
1 cm      7 cm
--------  = ---------
25 km    x km
Using cross products.
1 * x = 7 * 25
x = 175 km
