I need help with ratios

OpenStudy (anonymous):

the problem is

OpenStudy (paki):

yeah

OpenStudy (anonymous):

12 yd to 20 ft

OpenStudy (paki):

1 yard is equal to 3feets....

OpenStudy (anonymous):

So do 1 times 20

OpenStudy (paki):

so 12 yards will be eqaul to how many feets....?

OpenStudy (anonymous):

36

OpenStudy (paki):

good... now write it in ratio form....

OpenStudy (anonymous):

12:36

OpenStudy (paki):

yup then what will be the simplified form.... 12/36 = ...?

OpenStudy (anonymous):

3

OpenStudy (anonymous):

so the answer is 3:5

OpenStudy (paki):

no...

OpenStudy (paki):

1:3...

OpenStudy (paki):

12*1 = 12 12*3 = 36..... got it now...

OpenStudy (anonymous):

But on my test those are not the options

OpenStudy (anonymous):

The options are: 5:9 3:5 5:3 9:5

OpenStudy (paki):

these options are wrong ... its 1:3....

OpenStudy (anonymous):

But my test is never wrong I do not know what to do

OpenStudy (anonymous):

Did you simplify

OpenStudy (anonymous):

Use a ratio to compare the values. Simplify the ratio. 12 yd to 20 ft That's the problem.

OpenStudy (paki):

12 yr = 36 ft 12/36 = 1:3

OpenStudy (anonymous):

never mind can you help me with a different problem?

OpenStudy (anonymous):

The conservation club has 32 members. There are 18 girls in the club. What is the ratio of girls to boys in simplest form?

OpenStudy (paki):

18 girls...so there will be 14 boys.... ok...

OpenStudy (anonymous):

ok

OpenStudy (paki):

so write it in ratio form... and simplify....

OpenStudy (anonymous):

0.78

OpenStudy (paki):

18/14 = 9/7

OpenStudy (anonymous):

so the answer is 9/7

OpenStudy (paki):

yeah
