    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

    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"

    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 = ???
