Since only 1/10 of her income applies to all 5 charities, it would make sense to assume that 1/10 is strictly donated to the charities. Moreover, because we assume that, we must then divide 1/10 by 5, so that way we can get the amount that is donated to each charity. So you should get, 1/50 is equally donated to each charity out of the 1/10 of her income that is donated. Hopefully this helps.

All you have to do is multiply 1/10 * 5

the answer is 5/10
if u simplify 5/10 the final answer will be 1/2

An rectangular water tank has a base area of 56 sq. ft. and a height of 4 ft. Find its volume in cubic feet.

Answer: 224 cubic feet

Step-by-step explanation: If the base of the tank is 56 sq feet in area then the dimensions could be, (2,28) (4,14) (7,8) for example. However, it doesn't really matter. It's only important that the information we know is that it is area and there are two dimensions. Since volume is determined by base x width x height, we do 56 x 4. Or using one of the factored pairs that works, for example, 8 x 7 x 4 = 224.
