Answer:
10
Step-by-step explanation:
add them all up
10+7+13+10+10=50
divide by the number of terms (5)
50/5=10
To figure out the percentage you got correct, we need to set up fractional proportions.
We already have one fraction, 14/20.
Since we are looking for a percentage, we need to have a maximum total percentage that represents the total score.
100% is the maximum percentage for any total.
So we have our fractional proportions set;
14/20 : x/100
To solve for this, we need to cross multiply the numerator (top number) of one fraction by the denominator (bottom number) of the other fraction.
Let's try this!
14 • 100 = 1400
20 • x = 20x
Now that we have our products, set them as an equation.
20x = 1400.
To solve for x, we need to divide both sides by 20.
20x / 20 = x
1400 / 20 = 70.
You are left with:
x = 70.
Your answer is:
If you get 14/20 on a test, you would get 70% of the questions correct.
I hope this helps!
