Last one and first. You can find out why by isolating the cube root and cubing both sides.
2/7 as a fraction rounds to 0.3
0.3 * 3 = 0.9
3 x 2/7 is less than 3
Answer:
Answer is 3/4
Step-by-step explanation:
Solution:
The gas can is filled at the rate of 320 cubic inches per minute.
The can is 10 inches long, 8 inches wide, and 12 inches high.
So volume of the can=10 in*8 in *12 in
![\text{Volume of can }=960 \ in^3\\](https://tex.z-dn.net/?f=%20%5Ctext%7BVolume%20of%20can%20%7D%3D960%20%20%5C%20in%5E3%5C%5C%20)
Time required to fill the can![=\frac{960}{320}=3 \ minutes\\](https://tex.z-dn.net/?f=%20%3D%5Cfrac%7B960%7D%7B320%7D%3D3%20%20%5C%20minutes%5C%5C%20%20)
Hence Time required to fill the can =3 minutes.
Make them the same denominator like 2/3 and 4/6 you can either simplify 4/6 t0 2/3 or do 2/2 * 2/3 and get 4/6
