Seth uses a school camera to take pictures for the yearbook and for the school paper. Last
month he took 270 pictures for the yearbook and 180 pictures for the school paper with this
camera. Which proportion can be used to determine p, the percentage of the total number of
pictures he took that were for the yearbook?
P/100 = 270/450
To determine the percentage of the total number of pictures Seth took that were for the yearbook, we first need to find the total number of pictures he took.
The total number of pictures Seth took can be found by adding the number of pictures he took for the yearbook to the number of pictures he took for the school paper: 270 + 180 = 450.
Now, to calculate the proportion that represents the percentage of pictures for the yearbook, we can set up the following equation:
(p/100) = (270/450)
Here, p represents the percentage of pictures for the yearbook, and we divide 270 (the number of pictures for the yearbook) by 450 (the total number of pictures) to find the fraction.
To solve for p, we can cross-multiply:
450p = 270 * 100
Now, divide both sides of the equation by 450 to isolate p:
p = (270 * 100) / 450
Calculating this expression will give us the value of p, the percentage of the total number of pictures Seth took that were for the yearbook.
