1. The ratio of a wire that is cut in to 2 is 5:9
The longer piece was 25cm. Now, find the total length and the length of the shorter wire.
=> 5 : 9 = x : 25
=> First, let’s convert it to fraction
=> 5 = 9
x 25
=> 25 (5) = x (9)
=> 125 = 9x
=> 125 / 9 = 9x / 9
=> 13.9 = x
Thus the ratio is approximately 5 : 9 = 13.9 : 25
