Multiple 6 with numbers inside paranthesis:
12x - 66 + 15 = 21
add 66 fhen substrack 15 from both sides :
12x = 72 divide both sides with 12:
x = 6
Firs you need to convert the mixed numbers to decimals (left to right): 4.25; 4.125; 5.909091; 4.166667.. Then you organize them from least to greatest: the 4 as the whole number comes first, adding from the greater place values later; and then the 5 as it's the biggest number.. which makes the order:: 4.125, 4.166667,4.25, 5.909091.. (sorry if explained the way of how kind of bad.. I'm not very good at explanations, but I know my math..)

Answer:17.3964 males 7.6035 females
Step-by-step explanation:
The first way to calculate the expected uses the marginal percentages. If sex is not related to flavor preference, you would expect the same percentages of males to prefer the same flavors as females. Since overall 20.71% prefer vanilla, you would expect 20.71% of males to prefer vanilla. Now, 20.71% of 84 people is 17.3964, so this is how many males you would expect to prefer vanilla. You would also expect 20.71% of the females to prefer vanilla, which is 17.6035. So you'd expect 17.3964 males and 17.6035 females to prefer vanilla.
