Question

Arrange in decreasing order
7.3,7 1/2,7 1/5

5.1,1.5,0.5,5.0

Answer 1

To arrange the numbers in decreasing order, we first convert all the fractions to decimal form where necessary.

1. For the first group:
- \(7.3\) remains \(7.3\)
- \(7 \frac{1}{2} = 7 + 0.5 = 7.5\)
- \(7 \frac{1}{5} = 7 + 0.2 = 7.2\)

Now we have: \(7.3, 7.5, 7.2\)

Arranging in decreasing order:
- \(7.5\)
- \(7.3\)
- \(7.2\)

So, the first group in decreasing order is: **7 1/2, 7.3, 7 1/5**.

2. For the second group:
- \(5.1\) remains \(5.1\)
- \(1.5\) remains \(1.5\)
- \(0.5\) remains \(0.5\)
- \(5.0\) remains \(5.0\)

Now we have: \(5.1, 1.5, 0.5, 5.0\)

Arranging in decreasing order:
- \(5.1\)
- \(5.0\)
- \(1.5\)
- \(0.5\)

So, the second group in decreasing order is: **5.1, 5.0, 1.5, 0.5**.

Final result combining both groups:
1. First group: **7 1/2, 7.3, 7 1/5**
2. Second group: **5.1, 5.0, 1.5, 0.5**
