What two numbers at to 1 and multiply to 12

What are you trying to say? It seems that the question is not making sense.

Two numbers that 
add to 1
multiply to 12

i wonder if it is -12 because
-3 + 4 = 1
-3 × 4 = -12

There cant be any other solutions, im assuming it should be -12

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
