#2.5 xx t = 2.5t#


The word product means the answer to a multiplication.

Look for the word 'AND' because that will tell you which two numbers are multiplied together. (The product of 2 AND 3 is 6)

In this example the two numbers being multiplied are 2.5 and an unknown number, just called #t#.

The expression is: #2.5 xx t = 2.5t#

This is as far as we can go. We cannot write an equation, because we have not been given the answer to the multiplication.
