Answer: 0.78 and 39/50
<h3>
Explanation:</h3>
What we know:
- We need to find 78% as a fraction and decimal
How to solve:
The decimal is easy enough, and then the fraction can be found from there. D will represent decimal, p will represent percentage, and F will represent fraction.
<h3>
Process:</h3>
Decimal
Set up equation D = p / 100
Substitute D = 78% / 100
Simplify D = 0.78%
Remove % sign D = 0.78
Fraction
Set up equation F = p / 100
Substitute F = 78% / 100
Remove % sign F = 78 / 100
Simplify if needed F = /2 /2
F = 39 / 50
Solution: 0.78 and 39/50
Check:
Multiply the decimal by 100 to check the decimal
0.78 x 100 = 78; 78%
Divide the fraction to check the fraction
39/50 = 0.78; see above
Start by multiplying both sides by R to isolate V².
V² = P·R
Now, take the square root of both sides to get V.
V = √PR
Answer:for the first one, you should probably do a table of values then answer the question, i usually find that helpful
Step-by-step explanation:
If you are just dividing percent's, then each grade would have 12.5 percent.
