5/2 + 5/7
2*7=14
35/14+10/14
45/14 or 3 3/14
Ratio 1:3 can be written as 1/3
sale price / original price : 1/3 = x / 81
this is a proportion, so we cross multiply
(3)(x) = (1)(81)
3x = 81
x = 81/3
x = 27 <== sale price
and notice that 1/3 = 27/81...these are equivalent fractions because that is what proportions are, equivalent fractions

The speed of the wind as they travel is 105 miles per hour.
<h3>
Speed</h3>
Speed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let s represent the speed of the wind. Hence:
(525 - s)5 = 2100
s = 105 mph
The speed of the wind as they travel is 105 miles per hour.
