Math equation about words per minute

Question

In 7 minutes, Elsa can type 28 words. What is her rate in words per minute?

Answer 1

7 minutes is your time

28 is the number of words

ratio or equation we want is words per minute so we take the number of words and divide by the number of minutes

Let “x” be # of words per minute

7 minutes * x words/minute = 28 words

x words/minute = 28 words/7 minutes

x words/minutes = 4 words per minute

**** note that the units on one side equal the units on the other side

the equal sign means both words and numbers must be equal on each side
