For these types of problems, you multiply straight across. You multiply the numerators (the numbers above the line) together, and you multiply the denominators (the numbers below the line) together. For the numerators, 4x11=44. For the denominators, 9x4=36. So your answer is 44/36.
if u take out the 4 0s in 320.000 u will get 32 if u take out the percent of 23% u get 23 now mutiply 32 and 23 now u get 736 now add 3 0s then you have your answer
