This is simple. It wants 65% of 160, which is the same as saying (65/100) * 160, or 0.65 * 160. This is 104.

If you want a method easier to use without a calculator, as above use 160/100 * 65, which amounts to the same thing. [=1.6*65 = 104]

One of the people is working for 1/2 a day's work and another 1/3 a day's work. You have to add 1/2 and 1/3 together to find out how long the third person worked because it is going to be the whole day minus what the first and second people have already done. 1/2 is equivalent to 3/6 and 1/3 is equivalent to 2/6. 3/6 + 2/6 = 5/6. This means that the third person spent 1/6 of their time on the project, which makes it a total of one day's work, C.

Easy... there are two ways to solve this:

One: Divide 32 by 40. You now have one percent. Multiply by 100.

32/40 = 0.8
0.8 * 100 = 80

Two: Divide 100 by 40. Multiply by this 'ratio' of the current number to the whole number to find the whole number.

100/40 = 2.5
32 * 2.5 = 80

I prefer the first method, as it is easier to follow logically; however, the second is more common.

= 10/3 - 12/5

= (50-36)/15

= 14/15
