Given
The size of fire ant is 4
The size of crab spider is 5
Now John wants to magnify the image of both the fire ant and the crab spider so that they appear the same size.
So we know that
The multiples of four is 4 is 4, 8, 12, 16, 20, 24,...
The multiple of five is 5 is 5, 10, 15, 20, 25,....
Their common multiple is 20.
So the image of both the fire ant and the crab spider should be magnified to 20 so that they appear the same size.
Therefore, for the fire ant = 20 / 4 = 5 times
for the crab spider = 20 / 5 = 4 times
Thus the fire ant should be magnified 5 times
the crab spider should be magnified 4 times
so that they the same size of 20.
