Depending on the type of numbers you are considering, (ex: fractions, decimals, whole numbers) there can be multiple or even a limited amount of possibilities. If you are using whole number however this can be achieved by multiplying 1 x 99 = 99, or 3 x 33 = 99. Hope this helps :) Best of luck.
99
(33,3)(11,9)
1 x 891, 3 x 297, 9 x 99, 11 x 81, 27 x 33
11 and 9
1 x 198, 2 x 99, 3 x 66, 6 x 33, 9 x 22, 11 x 18
99
(33,3)(11,9)
33 x 3 = 99
1 x 891, 3 x 297, 9 x 99, 11 x 81, 27 x 33
-99 and 146
There are two combinations of numbers when multiplied together are equal to 15. 1 x 15 = 15 and 3 x 5 = 15.
97 and 2
11 and 9
1 x 198, 2 x 99, 3 x 66, 6 x 33, 9 x 22, 11 x 18
99
9x11
99 multiplied by 99 is equal to 9801. This can be calculated by multiplying the two numbers together using the standard multiplication algorithm, where each digit in the second number is multiplied by each digit in the first number and then the results are added together. In this case, 9 multiplied by 9 is 81, so the result is 9801.
