To arrange the given fractions and decimals in descending numerical order, we first need to convert everything to a common format (either to decimals or to fractions) for easier comparison.
Let's convert the fractions and mixed numbers to decimals:
- 0.733 - already a decimal.
- 0.923 - already a decimal.
- 1 2/5: Convert to decimal.
- 2/5 = 0.4, so 1 + 0.4 = 1.4
- 17/20: Convert to decimal.
- 17 ÷ 20 = 0.85
- 15/18: Simplify first (if possible).
- 15/18 = 5/6; convert to decimal.
- 5 ÷ 6 = approximately 0.8333
Now, we have:
- 0.733
- 0.923
- 1.4 (from 1 2/5)
- 0.85 (from 17/20)
- 0.8333 (from 15/18)
Now, we can order these in descending order:
- 1.4
- 0.923
- 0.85
- 0.8333
- 0.733
Thus, the descending order is:
1 2/5, 0.923, 17/20, 15/18, 0.733
