What is a REAL LIFE example of a Composite Number concept? Explain

Question

I have written 4 friends share 1 large pizza, 16 pieces, equally how much pizza does each friend get?

Facts: 16 slices to 1 pizza, 4 friends. divide

each friend gets 4 slices.

Is this a good example?

Answer 1

The idea of a composite number is that it is a product of primes.

A possibly better example would be: one pizza was divided into 6 slices and 2 are left;

a second pizza was divide into 8 pieces and 2 are left.

How much pizza s left?

(1/3)+(1/4) = 7/12

The lowest common denominator 12 is composite of 2*2*3.
