A number * by -12.3 is -73.8

Question

Write as an equation. A number multiplied by -12.3 is -73.8

Answer 1

If we let x represent the unknown number, then multiplying by -12.3 would be represented by: -12.3x

The word "is" can be represented with an equal sign: -12.3x = -73.8

To solve for x, divide both sides of the equation by -12.3:

-12.3x /-12.3 = -73.8 /-12.3

x= 6

Remember that a negative number divided by a negative number gives you a positive result. Here that is 6.
