if 4/7 of a circle is shaded and another 1/3 of it is also shaded..how much of it is not shaded?
anonymous
  • anonymous
10/21? LOL I have no idea. :(
anonymous
  • anonymous
2/21....(4/7)=(12/21) & (1/3)=(7/21)....so, (12/21)+(7/21)=(19/21). 1=(21/21). Therefore, (21/21)-(19/21)=(2/21)....(2/21) is the fraction of the circle that is not shaded, so that's your answer.

A bookstore had 72 copies of a magazine. Yesterday, it sold 1/4 of them. Today, it sold 1/6 of what remained. How many copies does the bookstore have left?
anonymous
  • anonymous
First you have to figure out what fraction of 96 were sold the last month..so, 96 (1/3) = 32. This means that after the first month there are 96-32=64 houses remaining. Then 3/8 of those houses were sold. So, 64(3/8)= 24 house. So, 24 houses were sold during the second month. Simply subtract that from 64 which is how many houses remained after the first month and you get 64-24= 40 houses.

You should be able to start catching on and doing them yourself. Try to figure out how I did the last one.

i can't do it .. im lost

You just have to think about the problem in segments. It always seems to give you a number to start with. For example 72 magazines in the last problem you gave me. And then you have to use the fractions (1/4) to figure out how many magazines were sold yesterday. Figure that out real quick. Message me how many books were sold after yesterday.
