OpenStudy (britanyashton):

Question: "what percent of left-handed people are girls?" Questions for you, from me: what is the total of left-handed people (2+2)? How many left-handed people are girls?

OpenStudy (anonymous):

4

OpenStudy (britanyashton):

ok how many left-handed are girls?

OpenStudy (britanyashton):

You can find that by looking at the chart

OpenStudy (anonymous):

so its 4 rite

OpenStudy (whpalmer4):

no. the chart looks like this: right-handed left-handed girls 8 2 boys 9 2 there are how many right-handed girls? how many right-handed boys? how many left-handed girls? how many left-handed boys?

OpenStudy (britanyashton):

the answer is going to be the number of girls that are lefthanded over the total number of people (boys and girls) that are left-handed. number of girls that are left-handed=2 Total number (boys and girls) that are left-handed=4 so, what is the fraction that models this relationship: # of girls left-handed ----------------------------------------------- boys and girls that are left-handed

OpenStudy (anonymous):

so wats the answer

OpenStudy (whpalmer4):

OpenStudy (anonymous):

OpenStudy (britanyashton):

yep and 2 girls out of that. so 2/4 which is what in decimal? .5

OpenStudy (anonymous):

yup so the answer is .5

OpenStudy (britanyashton):

in the hundreths place, round that .50

OpenStudy (britanyashton):

yes!

OpenStudy (anonymous):

o ok

OpenStudy (anonymous):

so should i put .5 or .50

OpenStudy (britanyashton):

put remember to round to the hundreths. since there are not numbers after that. place a zero there. which brings .50

OpenStudy (britanyashton):

they've been telling you to round to the hundreths place the entire thing, so round there this time. 50%

OpenStudy (anonymous):

ill have to put .5 it only allows me to put that ok so ima put 50%

OpenStudy (britanyashton):

yes. because .5 is a decimal, not a percentage.

OpenStudy (britanyashton):

If I find an instructional video for you on rounding, would you watch it?

OpenStudy (anonymous):

OpenStudy (britanyashton):
