Answer:
61.8 mm
Explanation:
If the photo of the ant is increased to 515% of its actual size, this means the size of the ant in the photo is:
515% = 515/100 = 5.15
So the ant in the photo is 5.15 times larger than its actual size.
To find the size of the ant in the photo, we can multiply its actual size by 5.15:
size of ant in photo = 12 mm x 5.15 = 61.8 mm
Therefore, the size of the ant in the photo is 61.8 millimeters.
