14. 10 5/18 – 8 5/6 =

15. 1/2 • –1 1/3 =

16. 5/8 ÷ 15/16 =

17. Write 13/4 as a decimal. Round to three decimal places

help me plz

10 5/18 = 9 23/18

8 5/6 = 8 15/18

9 23/18 - 8 15/18 = (9-8) + (23-15)/18 = 1 8/18 = 1 4/9

Or,

10 5/18 = 185/18
8 5/6 = 53/6 = 159/18
(185-159)/18 = 26/18 = 1 8/18 = 1 4/9

Do the others in like wise. Come back and show where you get stuck, if you do.

To solve each of these problems, you need to follow certain steps. Here's how you can find the answers:

14. To subtract mixed numbers, follow these steps:
- Convert the mixed numbers into improper fractions. In this case, 10 5/18 can be written as 183/18 and 8 5/6 can be written as 53/6.
- Subtract the fractions. 183/18 - 53/6 = (183 * 6 - 53 * 18) / (18 * 6).
- Simplify the fraction if possible. The answer is 53/18.

15. To multiply a mixed number by a fraction, you can convert the mixed number into an improper fraction and multiply the two fractions. Here are the steps:
- Convert the mixed number -1 1/3 into an improper fraction. It becomes -4/3.
- Multiply the fractions: 1/2 * -4/3 = (-4/6) = -2/3.

16. To divide fractions, you need to multiply the first fraction by the reciprocal of the second fraction. Here are the steps:
- Take the reciprocal of 15/16. It becomes 16/15.
- Multiply the fractions: 5/8 * 16/15 = (5 * 16) / (8 * 15) = 80/120.
- Simplify the fraction if possible. The answer is 2/3.

17. To convert a fraction into a decimal, divide the numerator by the denominator. Here is the step:
- Divide 13 by 4. The result is 3.25 (rounded to two decimal places).
