First, let's talk about how many eggs there are in a dozen.
1 dozen of anything = 12 of them .
Now, armed with that vital piece of information, let's do the problem.
Give Uncle Wilbert's age a name. Call it ' A '. (for 'age')
If you divide it by 4, you then have A/4 .
Then if you subtract 11 from that number, you have A/4 - 11 .
Now we can write an equation: A/4 - 11 = 12
Add 11 to each side of the equation: A/4 = 23
Multiply each side of the equation by 4 : A = 92 .
Uncle Wilbert is 92 years old.
Proof:
Divide it by 4 and you have 23 .
Then subtract 11 and you have 12 ... the number of eggs in a dozen.
