How do you write the algebraic expression: the product of 2.5 and a number t?

1 Answer

Jul 3, 2016

$2.5 \times t = 2.5 t$ $2.5 xx t = 2.5t$

Explanation:

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 $t$ $t$ .

The expression is: $2.5 \times t = 2.5 t$ $2.5 xx t = 2.5t$

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