Question

A photo of an ant in a science book is increased 515% as large as the actual size. If the ant is 16 millimeters, what is the size of the ant in the photo

Answer 1

The size of the ant in the photo is 88 mm

Explanation:

Here, we have the percentage increase = 515 %

Size of ant = 16 millimeters in real life,

Therefore, the size of the ant in the in the photo, is given by,

`(16 \, mm)/(100) = (y\, mm)/(550) = (16 * 550)/(100) = (y * 100 \, mm)/(100) \rightarrow 88 \, mm = y`

y = 88 mm

The size of the ant in the photo = 88 mm.

Answer 2

82.4 millimeters is the size of the ant in the photo

Explanation:

In this question, we are asked to calculate the size of an ant in a science book given the actual size of the ant and the percentage increase is the size of the ant in the book.

From the question, we can identify that the actual size is 16 millimeters

Now let’s find 515% of this to know the size to which it would be magnified in the science book.

That would be;

515/100 * 16 = 82.4 millimeters

Hence, this means the ant will have a size of 82.4 millimeters in the science book
