Answer:
Ants and by roughly 118,615,000mg greater.
Step-by-step explanation:
According to a quick online search, a regular house fly weighs on average 11.5mg while an ant weighs on average 3.5mg. Now that we have the average weight of each we can multiply this number by the quantity of each to find the approximate total weight.
Flies: 3,990,000 * 11.5mg = 45,885,000mg
Ants: 47,000,000 * 3.5mg = 164,500,000mg
Therefore, based on this calculation we can clearly see that the 47 million ants will have a greater mass and this mass would be approximately
164,500,000 - 45,885,000= 118,615,000mg greater
