During the first week of baseball season, the Boston Red Sox won 6 out of 8 games. How many of the 162 regular season games must they win to maintain this ratio? Round to the nearest game.

OpenStudy (anonymous):

162 / 8 * 6

OpenStudy (anonymous):

121.5 which is rounded to 122

OpenStudy (anonymous):

wait all it is, is division??

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

basically, you are taking 6/8 and expanding it to the scale of the larger number

OpenStudy (anonymous):

the ratio of 121.5/162 is exactly 6/8

OpenStudy (anonymous):

but wait when I divide 162 by (6x8) I get 3.375??

OpenStudy (anonymous):

it's not 162/(6*8), it's 162 / 6 * 8

OpenStudy (anonymous):

so you divide 162 by 6, then multiply the result by 8

OpenStudy (anonymous):

that gives me 216

OpenStudy (anonymous):

divide it by 8 sorry, then multiply by 6

OpenStudy (anonymous):

basically you're finding out what 1/8th of 162 is, and then multiplying it by 6 to find out what 6/8ths of 162 is

OpenStudy (anonymous):

ooooh ohkay!!

OpenStudy (anonymous):

you could also just multiply 162 by (6/8)

OpenStudy (anonymous):

\[\frac{ (162) * 6 }{ 8 }\]

OpenStudy (anonymous):

is what it all amount's to

OpenStudy (anonymous):

ok thanks!! these ratio"s are tricky but this helps
