<h3>Word Problem</h3>
When we see the word "of" in a mathematic expression, it simply means multiplication
Hence we have the mathematical expression for the word in our example as
2/3*n = 42
re-write
2n/3 = 42
cross multiplying we have
2n = 42*3
2n = 126
divide both side by 2 we have
n = 126/2
n = 63
