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>

How do you convert repeating decimals to fractions?
Wittaler [7]

Answer:

Step-by-step explanation:

A repeating decimal, also known as a recurring decimal, is a decimal number that has a digit or digits that infinitely repeat at regular intervals. Repeating decimals can be tricky to work with, but they can also be converted into a fraction. Sometimes, repeating decimals are indicated by a line over the digits that repeat. The number 3.7777 with 7 repeating, for instance, can also be written as 3.7. To convert a number like this to a fraction, you write it as an equation, multiply, subtract to remove the repeating decimal, and solve the equation.  hope this helps
