How Do You Solve a Word Problem by Dividing Monomials?

Calculate the ratio of the height to the base for the triangle in the diagram. Write your answer as a monomial in simplest form.

Summary

  1. A ratio can be represented as a fraction, so for us the fraction is the height divided by the base
  2. Use the associative property to move the variables around in the denominator
  3. Split up the variables so that each variable has its own fraction by itself
  4. Instead of dividing variables, you can just subtract their exponents to find the answer

Notes

    1. The height is 32a3b7c2
    2. The base is 4ac4b5
    3. 'a', 'b', and 'c' are variables
    1. The height is 32a3b7c2
    2. The base is 4ac4b5
    3. 'a', 'b', and 'c' are variables
    1. The ratio is 32a3b7c2 over 4ac4b5
    2. 'a', 'b', and 'c' are variables
    1. 'a', 'b', and 'c' are variables
    1. 'a', 'b', and 'c' are variables
    2. Originally the denominator has the variables in the order, a, c, b
    3. We switch the b5 and c4 variables so that the order is now a, b, and c
    1. 'a', 'b', and 'c' are variables
    2. We are making each variable its own fraction, so that they will be easier to cancel out
    1. Instead of dividing variables you can use the quotient of powers to just subtract their exponents to find the answer
    1. So a3-1 is the same as dividing a3 by a
    2. 'a' is a variable
    1. So b7-5 is the same as dividing b7 by b5
    2. 'b' is a variable
    1. So c2-4 is the same as dividing c2 by c4
    2. 'c' is a variable
    1. 'a', 'b', and 'c' are variables
    2. c-2 is another way of writing 1 divided by c2
