What times what equals -83.2?
There are infinitely many pairs of numbers whose product is -83.2 For the simplest numbers - ignoring the decimal point and negative sign gives the number 832 which has the factor pairs: 1 × 832 2 × 416 4 × 208 8 × 104 13 × 64 16 × 52 26 × 32 If you make one of each pair of numbers negative, and divide one of the numbers by 10 you will get a pair of numbers whose product is -83.2, examples: -1 × 83.2 2 × -41.6 -2 × 41.6 -0.2 × 416 2.6 × -32 -2.6 × 32 -26 × 3.2 etc.
