Answer:
Step-by-step explanation: The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(,
) = 100
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(×
)+(
×
)=?
Complete the multiplication and the equation becomes
+
=?
The two fractions now have like denominators so you can add the numerators.
Then:
=
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 80 and 100 using
GCF(80,100) = 20
=
Therefore:
+
=

There are 19 people total, and groups of four are being asked of us. We can use the formula for permutations or combinations.
Permutations:
Combinations:
Where in both scenarios, there are <em>n</em> objects being chosen at <em>r</em> times.
19 P 4 is 93024
19 C 4 is 3876
It all depends on whether order matters with group placement; if it does, your answer is 93024, if not, then your answer is 3876.
