This problem actually has no solution. Any two numbers that will add to 6.5 will be too small to produce a multiple equal to 64.

However, for problems like this in general, writing the question as a formula might help you solve it.

1. Assume the numbers are x and y.

2. Write two equations (two unknowns and two equations gives you enough information to solve).

-The first part, "two numbers added equal 6.5" can be written as x + y = 6.5

-The second part, "two numbers multiplies equal 64" as xy = 64

3. Manipulate the equations to solve. For example:

y = 64/x

x + y = x + (64/x) = 6.5

4. Solve for x, and then use x to find y using either of the original formulas.

You can multiply two decimal numbers together and get an answer less than either one of the numbers you multiplied?

Yes, but you need two positive numbers less than one. 0.5 * 0.5 = 0.25 for instance. (half of a half is a quarter)


What two numbers when added equal 30?

half of 30 is 15, so 15 added to 15 would equal 30. if you go from there and add one number and subtract one number from each 15 (14 plus 16, 13 plus 17, ect...all the way to 0 plus 30) these numbers will also total to 30.
