HOW DO YOU REWRITE 72 AND 81 IN TWO A FRACTION

OpenStudy (anonymous):

I MEAN FActors

OpenStudy (anonymous):

Using the GCF you found in Part B, rewrite 72 + 81 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. Show your work. (4 points)

OpenStudy (anonymous):

PART B: THE GCF OF 72 and 81 is 9

OpenStudy (zbrandz23):

What two numbers will equal 72 when multiplied and what two numbers will 81 when multiplied

OpenStudy (zbrandz23):

You're on the right track

OpenStudy (anonymous):

i dont get what they ask

OpenStudy (zbrandz23):

I just started learning Greatest Common Factor Today. Im kinda getting it

OpenStudy (anonymous):

your a 6 grader

OpenStudy (zbrandz23):

no

OpenStudy (zbrandz23):

write out the multiples of 9

OpenStudy (anonymous):

then how are your learning that today

OpenStudy (zbrandz23):

72 and 81 are factors of 9

OpenStudy (zbrandz23):

I had a similar question like yours that I posted and @StudyGurl14 told me it was part of the GCF Concept

OpenStudy (anonymous):

oh ok

OpenStudy (zbrandz23):

What else is the question asking?

OpenStudy (anonymous):

thats it

OpenStudy (anonymous):

Question 1 (Essay Worth 10 points) (03.01 MC) Part A: Find the LCM of 5 and 12. Show your work. (3 points) Part B: Find the GCF of 72 and 81. Show your work.

OpenStudy (zbrandz23):

You're doing a test?

OpenStudy (anonymous):

yes

OpenStudy (studygurl14):

LCM of 5 and 12 \(\large\tt Multiples~of~5:\) \(\tt 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, \color{red}{60}, 65...\) \(\large\tt Multiples~of~12:\) \(\tt 12, 24, 36, 48, \color{red}{60}, 72...\)

OpenStudy (studygurl14):

That's cheating @longboardlife

OpenStudy (anonymous):

what i dont get it

OpenStudy (anonymous):

IM NOT CHEATIN I JUST DONT GET THE QUESTION

OpenStudy (anonymous):

I KNOW ITS 12 IN EED HELP ON QUESTION C

OpenStudy (anonymous):

Part C: Using the GCF you found in Part B, rewrite 72 + 81 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. Show your work. (4 points)

OpenStudy (zbrandz23):

Basically when you're looking for the LCF you write out the multiples of each of the numbers that they give you and once you find a matching number from that multiple then you circle it or undeline it and that would be your LCF.

OpenStudy (anonymous):

HOW DO YOU REWRITE 72 AND 81 INTO A FACTORS

OpenStudy (zbrandz23):

You rewrite 72 and 81 into two small numbers what are two numbers that make 81 when multiplied together and whats two numbers make 72 but you're keeping one number from 81.

OpenStudy (anonymous):

OH OK CAN YOU SAY ON THOUGH

OpenStudy (zbrandz23):

You're welcome and what?

OpenStudy (anonymous):

9*8 = 72

OpenStudy (zbrandz23):

Correct:D

OpenStudy (anonymous):

am i roght is it like that

OpenStudy (zbrandz23):

Yes

OpenStudy (anonymous):

9*9=81
