There are 6,657 marbles in a jar. approximately 34% are white, and the rest are black. how many black marbles are there?

So if there are 34% white marbles, that means that 66% are black (100% - 34% = 66%).

If 100% = 1.00, then 66% = 0.66.

Now, you just need to multiply the total by this decimal in order to find the number of black marbles:

6657 x 0.66 = 4393.62, which can be rounded to 4394

Therefore, there are about 4394 black marbles in the jar.

I hope this helps!
