A photograph that measures 5 in wide by 7 in. high is reduce to fit into a space that is 1 in. high. Which proportion can be used to find W, the width of the reduced photo
W/5 = 1/7
Solve for W.
Salina can run 2 miles in 24 minutes. At this rate, how long will it take her to run 10 miles
To find the width of the reduced photo, we can set up a proportion using the given information.
Let's denote the width of the reduced photo as W.
The original photo measures 5 inches wide by 7 inches high. So, we can set up the following proportion:
Original width / Original height = Reduced width / Reduced height
5 inches / 7 inches = W inches / 1 inch
To solve for W, we can cross-multiply and then solve for W:
5 inches * 1 inch = 7 inches * W inches
5 = 7W
Divide both sides by 7:
5/7 = W
So, the proportion to find the width of the reduced photo is:
5/7 = W
To find the width of the reduced photo, we can set up a proportion using the given measurements.
A proportion is an equation that states two ratios are equal. In this case, we want to compare the width of the original photo to the width of the reduced photo.
Let's denote the width of the original photo as "W" and the width of the reduced photo as "w" (lowercase 'w').
The given measurements are as follows:
Width of the original photo (W) = 5 inches
Height of the original photo = 7 inches
Height of the reduced photo (h) = 1 inch
Now we can set up the proportion using these values:
W/7 = w/1
To find the width of the reduced photo (w), we can cross-multiply and solve for w.
W/7 = w/1
w = (W * 1) / 7
w = W/7
So, the proportion that can be used to find the width of the reduced photo is W/7 = w/1.
