Answer 2

Given - Ratio of 2 pieces of rod

Find - Length of the longer piece

Solution - The length of the longer piece is 63.7 centimetres.

Let the length of the longer piece be 7x and the length of the smaller piece be 5x.

As per the question-

5x = 45.5

x = 9.1 centimetres

So, the length of the longer piece = 7*9.1

Length of longer piece = 63.7 centimetres.

Therefore, the length of the longer piece is 63.7 centimetres.
