There are 250 students in the 6th grade 45% of the eat lunch in 4th period how many students eat lunch in 4th period?
horrorfan [7]

Answer: 112.5

Step-by-step explanation:

The question really is asking whats 45% of 250

1. Calculate 10% of the total

2. Calculate 5% of the total

3. Solve for 40% of the total

4. Add 5% of the total

1. 10% of 250

250 = 100%

*divide both sides by 10*

25 = 10%

2. 5% of 250

25 = 10%

*divide both sides by 2*

12.5 = 5%

3. 40% of 250

10% + 10% + 10% + 10% = 40%

25 + 25 + 25 + 25 = 40%

50 + 50 = 40%

100 = 40%

4. 45% of 250

100 = 40%

12.5 = 5%

100 + 12.5 = 40% + 5%

<em>112.5 = 45%</em>
