Answer 1

btw this is for @Mathmachine2021

Answer 2

Oh ok then
lmk if he cant solve it

Answer 3

hi

Answer 4

he couldn't post the question

Answer 5

Oh.. ok

Answer 6

OR SHE

it wont let me post stuff

Answer 8

im a boy :D

Answer 9

YAY! I GOT IT RIGHT THE FIRST TIME!

Answer 10

wha

Answer 11

You still need help?
@Mathmachine2021

Answer 12

yes please

Answer 13

im stumped

Answer 14

Alright so basically
we have to find the biggest number that can be divided evenly into 45 + 72

Answer 15

cause its:
Greatest
Common
Factor

Answer 16

\(\LARGE\frac{45}{?}+\frac{72}{?}\)
Which is the same thing as
\(42÷?\)
\(72÷?\)
Any idea now? @Mathmachine2021

Answer 17

gcf

Answer 18

hmmmmmmm

Answer 19

Yes
GCF =
```
>G-Greatest
>Common
>Multiple
```
Meaning that you have to find the biggest number that can be divided evenly into 45 + 72

Lets start with 42,
all you have to do is find what number can go into it evenly
but it has to be the biggest number possible

Answer 26

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Mathmachine2021

Oh woops
I misread
I thought it said 43 when it really said 45
my mistake

Answer 30

42*

Answer 31

So what do you think ?
which answer choice best fits?
@Mathmachine2021

Answer 32

(We're just talking about 45 right now)

Answer 33

the way you are saying it is diffrent from they way i leanred so im kinda confused

Answer 34

Sorry
I haven't done this \(\sf 3^{rd}\) grade work in a long time

Answer 35

oh ok

Answer 36

i just wanted the awnser because im doing a small quic rn

Answer 37

quiz*

Answer 38

Ok so
\(\LARGE\frac{45}{5}+\frac{72}{8}\)
Those are the biggest numbers that can be equally divided among the numerators
That is just another way of writing \(\bf 45÷5\) and \(\bf 72 \div 8\)
Now do you have any idea on what the answer is?

Answer 39

@Mathmachine2021???
