To find the number of pieces, divide the total length of the string by the length of each piece. In this case, the string is 25 1/2 inches long and each piece is 3/4 inch long. Dividing 25 1/2 by 3/4 will give you 34 pieces.

One third is a lot bigger than one eighth. Imagine you have two pieces of string that are exactly the same length. You cut one into three equal pieces. Each piece is one third of the original string. Say you take the other sting and cut into eight equal pieces. Each of those pieces is one eighth... and they are much smaller because there are so many more of them.

This will depend on how long you would like each piece to be. If each piece is to be 1 inch long, then 115 pieces could be cut. If each piece is 2 inches long, then 57 pieces with 0.5 inches left over If each pieces is 5 inches long, then 23 pieces and so on and so forth.

If you mean equal pieces it is a centimeter.

Put a string over the curved line. Measure the string. If you want to do it by calculations for some known function, use integration. Divide the curved line into many small pieces, so that each piece can be approximated by a straight line, and use Pythagoras' Formula for each piece: length = square root of (width2 + height2), using the width and height of the piece. In calculus books, you'll find methods that can get you an exact result in some cases.

The number of pieces in the whole is the reciprocal of the fraction which represents each piece.So if each piece is a seventh = 1/7, then the number of pieces in the whole is 1/(a seventh) = 1/(1/7) = 7.

If the pieces came from a solid object of uniform density then the ratio is the same for each piece. But if not, the ratios need to be calculated separately.
