OpenStudy (acxbox22):

oh so 20*3.15=63
OpenStudy (acxbox22):
exactly
how else can you represent 20 x 3.15?
OpenStudy (briellshaw):
put it in 20 groups??
OpenStudy (anonymous):
3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15
OpenStudy (acxbox22):
for example:
2 x 5 = 2+2+2+2+2 right?
so the same goes for
3.15 x 20
pretty much like @OrangeMaster said

so do i put it in 20 groups which means B. is the answer
OpenStudy (texaschic101):
no
OpenStudy (acxbox22):
if we put 3.15 into 20 groups we would divide 3.15 by 20
OpenStudy (anonymous):
Dividing is lessening the number, and we are looking to build the number.
OpenStudy (acxbox22):
what option adds 3.15 20 times?

0.1575
OpenStudy (texaschic101):
example :
1 gal = 3.15
2 gal = 3.15 + 3.15
3 gal = 3.15 + 3.15 + 3.15
and so on
does that help ?
OpenStudy (briellshaw):
OH C. is the answer
OpenStudy (acxbox22):
yes, good job
because 15 cents doesn't sound like a realistic cost for 20 gallons of gas
OpenStudy (briellshaw):
okay thank you all
