Or did you not know how to turn a fraction into a decimal? Literally all you do is divide the numerator by the denominator (the top part by the bottom part)

1) put .1125 over 1.

2) to get rid of the decimal, multiply both parts of the fraction by 10,000.

3) Which gives you 1,125/10,000

4) To simplify, divide both parts by the greatest common factor. In this case, it happens to be 125.

5) 1125/125 = 9, 10000/125 = 80  So the final answer is 9/80.

5/(5+4)*918 = 510 girls

There are 5 girls for every 4 boys so there are 5 girls per 9 total people. If you set up the proportion 5/9 = x/918, the solution is 510.

There are other ways to do this problem, this is just one way.

since 13g/21cc simplifies to 0.619 g/cc, it has less density than the Isopropyl alcohol, and thus will float.

Jonas gets an orange, 5/11 chance. Since Jonas took a fruit from the basket, subtract 1 from the number of oranges as well as from the total number of fruit. Beth gets an apple, 4/10 chance.

Multiply the two probabilities together.

5/11 * 4/10 = 20/110 = 2/11
