OpenStudy (phi):

what did you get ?

OpenStudy (phi):

to do these, remember "per" translates to divide.

OpenStudy (anonymous):

So I do 4 / 26 for A ?

OpenStudy (phi):

yes miles per minute --> miles/ minutes or here, 4/26

OpenStudy (phi):

change to a decimal and round to the nearest 100th

OpenStudy (anonymous):

4 / 26 = 0.1638 so rounded would be 0.17? @phi

OpenStudy (skullpatrol):

4/26 = 0.1538

OpenStudy (phi):

is your calculator broken ?

OpenStudy (anonymous):

What lol?

OpenStudy (phi):

also, when you round, look at the 3rd digit. if 4 or less, round down (not up) here 0.1538 the 3 is 4 or less, so round down

OpenStudy (anonymous):

So the answer for A is 0.15?

OpenStudy (phi):

yes

OpenStudy (anonymous):

How would I do B?

OpenStudy (skullpatrol):

same idea

OpenStudy (phi):

hopefully you have the idea: look for x per y and figure out x/y where x and y are units

OpenStudy (skullpatrol):

"per" means " for each"

OpenStudy (anonymous):

12 / 27 ?

OpenStudy (anonymous):

B is 0.44?

OpenStudy (skullpatrol):

27/12

OpenStudy (anonymous):

2.25 ?

OpenStudy (skullpatrol):

yes

OpenStudy (skullpatrol):

2.25 pounds for each dollar

OpenStudy (anonymous):

OpenStudy (skullpatrol):

OpenStudy (skullpatrol):

ok, do you understand what "per" means?

OpenStudy (anonymous):

yes.

OpenStudy (skullpatrol):

what?

OpenStudy (anonymous):

14 / 4 ? or 4 / 14 ?

OpenStudy (skullpatrol):

the question asks for "per hour" so that means divided by hours

OpenStudy (anonymous):

So 14 / 4 ?

OpenStudy (skullpatrol):

:D

OpenStudy (anonymous):

A = 3.5 ?

OpenStudy (skullpatrol):

yes

OpenStudy (skullpatrol):

$3.5/hr

OpenStudy (skullpatrol):

You need to keep track of the "units"

OpenStudy (anonymous):

And is B = 0.11?

OpenStudy (anonymous):

Or B = 8.83 ?

OpenStudy (skullpatrol):

the are asking for acre/pound

OpenStudy (anonymous):

So 0.11?

OpenStudy (skullpatrol):

6 acre / 53 pounds

OpenStudy (skullpatrol):

You NEED to write the units of acre and pound
