Question

john wants to magnify the image of a fire ant and a crab spider so they appear the same length how many times their actual sizes fire ant 4 crab spider 5 he need to magnify each image

Answer 1

He needs to magnify the fire ant 5 times, and the crab spider 4, because 20 is a common multiple for both.

Answer 2

Answer:

fire ant = 5 times

crab spider = 4 times

Step-by-step explanation:

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.
