Answer:
5/36
Step-by-step explanation:
Colin's fraction of the prize is ...
5/(3+4+5) = 5/12
1/3 of that is ...
(1/3)(5/12) = 5/36
Colin gave 5/36 of the prize to charity.
2dimentional figure has 2 dimentions, legnth and width it is like an image on the computer screen
3d has depth, like a box
2d vs 3d is like a sheet of paper vs a box
If 12 divided by 36 is 3 then multiply 15 by 3 to get 45 as the answer
The answer is
8(8.8 x 10^12) = <span>70.4 x 10^12
the answer is </span><span>A. 70.4 x 10^12</span>
Answer:
72 Wrong, so find how many are right with 135 total
Step-by-step explanation:
It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.
so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number. If it helps 8/15 is about 53%. just like 1/2 is half. So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.
so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72. So 72 wrong so al others are right, which you get with 135-72 = 63.
You could also do 135*(1-8/15) = 135 * 7/15. if you ever want to find something NOT part of the proportion you do 1 - that proportion.
