there are 1,920 pieces of pipe in a stockroom of these two fifths is 2 inch pipe 1/3 as 1/2 inch pipe 3/16 is 1 inch pipe and the rest are all having pipe how many pieces of half inch pipe are there?
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
To find the number of pieces of half-inch pipe in the stockroom, we need to calculate the fraction of the total number of pieces that represents half-inch pipe.
Let's break down the information given:
- Two fifths of the total number of pipes are 2-inch pipes.
- One-third of the total number of pipes are 1/2-inch pipes.
- Three-sixteenths of the total number of pipes are 1-inch pipes.
- The remaining fraction represents half-inch pipes.
First, let's calculate the total number of pipes in the stockroom:
Total pipes = 1,920
Next, we'll find the number of 2-inch pipes:
2-inch pipes = (2/5) * Total pipes
Now, let's find the number of 1/2-inch pipes:
1/2-inch pipes = (1/3) * Total pipes
Next, we'll find the number of 1-inch pipes:
1-inch pipes = (3/16) * Total pipes
To find the number of half-inch pipes, subtract the sum of 2-inch, 1/2-inch, and 1-inch pipes from the total number of pipes:
Half-inch pipes = Total pipes - (2-inch pipes + 1/2-inch pipes + 1-inch pipes)
Now we can substitute the values into the equation:
Half-inch pipes = 1920 - [(2/5) * 1920 + (1/3) * 1920 + (3/16) * 1920]
By simplifying the equation, we get:
Half-inch pipes = 1920 - (768 + 640 + 360)
After calculating the values inside the parentheses, we can subtract:
Half-inch pipes = 1920 - 1768
Finally, subtract to get the result:
Half-inch pipes = 152
Therefore, there are 152 pieces of half-inch pipe in the stockroom.
