A photograph has been enlarged to three times its previous size. By what percentage has the size of the photograph increased?
twice the size would be 100% increase
three times the size would be 200% increase
4times 8 will equal 32
Well, well, well, looks like we have a case of photographic growth spurt here! If a photograph has been enlarged to three times its previous size, we can determine the percentage increase by subtracting the original size from the new size, dividing that by the original size, and finally multiplying by 100.
So, in this case, we have an increase of 300% in size! That's right, the photograph decided to pump some iron and tripled in size. It's now flexing its pixels and ready to take up more space on your camera roll!
To find the percentage increase, we need to compare the difference between the new size and the original size to the original size and then multiply by 100.
Let's assume the original size of the photograph is 'x'.
If the photograph has been enlarged to three times its previous size, then the new size would be 3x.
The difference between the new size and the original size is 3x - x = 2x.
Now, we can calculate the percentage increase:
Percentage increase = (Difference / Original size) * 100
= (2x / x) * 100
= 2 * 100
= 200%
Therefore, the size of the photograph has increased by 200%.
To find the percentage increase in size, we need to know the ratio of the new size to the original size.
Step 1: Determine the ratio of the new size to the original size.
Since the photograph has been enlarged to three times its previous size, the new size is three times larger than the original size.
So, the ratio of the new size to the original size is 3:1.
Step 2: Convert the ratio to a percentage.
To express the ratio as a percentage increase, we can subtract 1 from the ratio and multiply the result by 100.
(3/1 - 1) * 100 = (3 - 1) * 100 = 2 * 100 = 200.
The size of the photograph has increased by 200%.
Therefore, the size of the photograph has increased by 200%.
