    Here is the answer x~ 24 2/5 inches (The answer was to be simplify. Round to the nearest 1/5 inch) I have know clue how they come up 24 2/5 inches

    since the denominator are the same, they cancel, so you're left with (6 7/8)x = (7 3/4)(21 3/5) change everything to improper (55/8)x = (31/4)(108/5) check my calculation (55/8)x = 837/5 x = (837/5)*(8/55) x = 6696/275 ....definitely check my calculations..

    Where does the 837/5 come from?

    \[\frac{31}{4} * \frac{108}{5} = \frac{837}{5}\] look at the link above it

    Then how do you figure this out: Suppose to round to the whole centimeter (6 7/8)y = ( 7 3/4)(58) ------- --------- 6 7/8 6 7/8

    I figure that one out but how would you do this one (7 1/4) y = (7 1/8)58) ------- --------- 7 1/4 7 1/4

    (7 1/4) y = (7 1/8)(58) (7 1/4) y = (413 1/4) y = 57

    (7 1/4) y = (7 1/8)(58) ^----^--- multiply together, you will get 413 1/4 (7 1/4) y = (413 1/4) y = (413 1/4) / (7 1/4) y = 413 / 7 y = 59 <-- correction, i meant to type 59 i'm sorry
