Taylor painted 9/2 square yards of wall with three gallons of paint .How many gallons of paint does it take to paint each square yard of wall?

shinedivneonebytime:

may some one please help me

shinedivneonebytime:

please im begging you

jimthompson5910:

Based on the given info, we can effectively make the equation 9/2 square yards = 3 gallons of paint If we multiplied both sides by 2, we then get 9/2 square yards = 3 gallons of paint 2*9/2 square yards = 2*3 gallons of paint 9 square yards = 6 gallons of paint Does that make sense so far?

shinedivneonebytime:

no not really

shinedivneonebytime:

im only in 6th grade

shinedivneonebytime:

lol

jimthompson5910:

I have this fraction |dw:1606690471391:dw|

jimthompson5910:

then I multiplied both sides by 2 so that the fraction cancels out |dw:1606690511319:dw|

jimthompson5910:

Hopefully that clears things up a bit

shinedivneonebytime:

why do you cancel it out

jimthompson5910:

because fractions are a pain to deal with and it's easier to work with whole numbers

shinedivneonebytime:

oh ok can you explain more

jimthompson5910:

ok so far we have 9 square yards = 6 gallons of paint This means 9 square yards of wall need 6 gallons of paint The goal is to find out how many gallons are needed for 1 square yard

shinedivneonebytime:

oh ok so whats the next step

jimthompson5910:

how can we turn the "9 square yards" into "1 square yard" ? hint: we'll have to divide both sides by some number

shinedivneonebytime:

divide by 9 ?

jimthompson5910:

yes

jimthompson5910:

what do you get when you do so?

shinedivneonebytime:

1 and umm

jimthompson5910:

yes you'll have "9 square yards" turn into "1 square yard" what does the "6 gallons of paint" turn into?

shinedivneonebytime:

ok so 6 gallons would turn into 1.5

shinedivneonebytime:

i think

jimthompson5910:

it looks like you divided 9 over 6, which is not correct

jimthompson5910:

You have to swap the order

shinedivneonebytime:

ok so it would be 23 simlified

jimthompson5910:

use your calculator to compute 6 divided by 9

shinedivneonebytime:

0.66 and 0.66 as a fraction is 33/50

jimthompson5910:

Does your teacher want the answer as a decimal? or as a fraction?

shinedivneonebytime:

fraction

jimthompson5910:

ok then you'll reduce 6/9 to get ____ (fill in the blank)

jimthompson5910:

tell me what you get

shinedivneonebytime:

um

shinedivneonebytime:

i dont know what do i do to answer this 6/9 to get ____

shinedivneonebytime:

hello

shinedivneonebytime:

helooo

shinedivneonebytime:

anyone

jakfishman:

wassup

shinedivneonebytime:

heloo

shinedivneonebytime:

lol

jakfishman:

hi

shinedivneonebytime:

what grades are everyone in im in 6

jakfishman:

lets not get off topic

shinedivneonebytime:

oh yea ok

jakfishman:

are there mc

jakfishman:

you get that???

shinedivneonebytime:

yea

jakfishman:

ok

shinedivneonebytime:

sorry i was afk i just dont know the next step

mxddi3:

ok so now, we cross multiply. do you know what that is?

shinedivneonebytime:

yes

mxddi3:

ok so no, here's a better way. |dw:1606692662109:dw| now what is 9/2(x) and what is 1(3)

jimthompson5910:

Sorry I was away To reduce 6/9 you need to divide both parts by the GCF

mxddi3:

^yes or we can do this. to find GCF, you need to list all the factors of 6 and 9. then,whatever the largest number they have in common is, divide by that, and you will get your answer.
