1/3 as 1/2 inch pipe... what is 1/3 of 1920 ?
I put it in wrong sorry there are 1920 pieces of pipe in a stockroom of these 2/5 is 2 in pipe 1/3 is 1½ inch pipe 3/16 is 1 inch pipe and the rest are half inch pipe how many pieces of half inch pipe are there?
number of 2 inch pipes = (2/5)(1920) = 768
number of 1½ inch pipes = (1/3)(1920) = ....
number of 1 inch pipes = (3/16)(1920) = ...
add them up, subtract from 1920 to get number of half inch pipes
2/5 *1920 = 768
1/3 * 1920 = 640
3/16* 1920 = 240
1648 = 768 + 640 + 240
1920 - 1648 = 272 other
