    convert each fraction to a decimal number and that will allow you to compare the numbers easier

    for example 1/30 = 0.0333333... 1/15 = 0.0666667 So we can see that 1/15 is larger than 1/30 since 0.0666667 is larger than 0.033333

    if you just had those two fractions, yes but you need to compare the rest of the fractions

    c is 0.1 and d is 0.13 so than it would be d than?

    that's the combination of choosing 7 things out of 9 basically it's asking "how many ways are there to choose 7 items out of 9 where order does not matter"

    well luckily we can take advantage of the fact that 9 C 7 = 9 C 2 9 C 2 = (9*8)/2 = ???

    5/12 = 5/12 1/6 = 2/12 1/4 = 3/12 ----------------- 5/12 + 1/6 + 1/4 is the same as 5/12 + 2/12 + 3/12

    5/12 + 1/6 + 1/4 + x = 1 is the same as 5/6 + x = 1 Now subtract 5/6 from both sides to isolate x 5/6 + x - 5/6 = 1 - 5/6 x = 1 - 5/6 x = ???
