<h3>How to calculate the number of custome?</h3>
From the information, the number of costumes she can alter varies directly with the amount of time spent working.
Since Belinda can alter four costumes in one hour, let the number of costumes she can alter in four and a half hours be represented by x.
This will be:
1/4 = 4.5/x
Cross multiply
x = 4.5 × 4.
x = 18
The number is 18.

Answer:
5. 43 / 6
6. 8.027778
2. -0.167
4. 1.5
Step-by-step explanation:
5. Conversion a mixed number to a improper fraction: 9 2/3 = 9 · 3 + 2 /3 = 29/3
Conversion a mixed number to a improper fraction: 2 1/2 = 2 · 2 + 1 /2 = 5/2
Subtract: 29/3 - 5/2 = 29 · 2 / 3 · 2 - 5 · 3 / 2 · 3 = 58 / 6 - 15 / 6 = 58 - 15 / 6 = 43 / 6
6. 2 4/9 + 5 7/12 = 289 / 36 = 81 / 36 = 8.027778
2. 3/4 - 11/12 = -1 / 6 =-0.1666667
4. 1 9/10 - 2/5 = 3 / 2 = 11 / 2 = 1.5
