x/100 = 5/35

Is/of = %/100 plug the numbers in 24/x = 16/100 then cross multiply then you get 2400 = 16x so you get x by itself so you would have to divide by 16. 2400/16 = 16x/16 the 16 on the x side cancel out so you get x = 150 (I used proportions)
Answer:
840 ways.
Step-by-step explanation:
For the first jar, you have 7 marbles to put in.
For the second, you now have 6 marbles to put in.
For the third, you have 5 marbles.
For the fourth, you have 4 marbles.
7 * 6 * 5 * 4
= 42 * 20
= 840 ways.
Hope this helps!
The answer is
4.0000000000006667
To solve this problem you have to set up a proportion. To form one side of the proportion you use "is over of" meaning what number represented by is, in this case 18, is placed over the number represented by of, 3000.
Since you are finding the percent of something, youre x value is placed above "100" because percent values are most commonly out of 100%.
So now your proportion will look like
To solve the proportion you cross multiply and divide. So you multiply 100 and 18 since they are crossed from each other, then divide 1800 by 3000. The answer is .6. 18 is .6% of 3000.
