1 or 5 depends she could fill with just one
Well, I actually did the entire calculations until I figured out that its very simple, and I didn't need to!
If she has already saved 6%, then to find how much she still needs to save, we subtract 100% from 6%.
So Nina still has to save 94% of the total cost to get the bike.
Answer:
2/21
Step-by-step explanation:
We start out with a full tank. Once the trucks take from it, it is down to 1/3 of a tank. Therefore,
![\frac{3}{3} -\frac{1}{3} =\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B3%7D%20-%5Cfrac%7B1%7D%7B3%7D%20%3D%5Cfrac%7B2%7D%7B3%7D)
So the trucks took 2/3 of the gas.
If there were 7 trucks and we need to know how much of that 2/3 was taken by each truck, we divide 2/3 by 7:
![\frac{\frac{2}{3} }{7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B2%7D%7B3%7D%20%7D%7B7%7D)
When dividing fractions, we bring up the lower fraction and flip it and multiply:
![\frac{2}{3}*\frac{1}{7}=\frac{2}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%2A%5Cfrac%7B1%7D%7B7%7D%3D%5Cfrac%7B2%7D%7B21%7D)
The answer to this is question is C
