Correct

HanAkoSolo (jamierox4ev3r):

Just think of this like a fraction. You want to get it as simplified as possible

likeabossssssss (likeabossssssss):

@hzro can u explain how

HanAkoSolo (jamierox4ev3r):

\(\Large\frac{28}{35}\) There is a number that both are divisible by. This is called finding the GCF (Greatest Common Factor)

likeabossssssss (likeabossssssss):

28/35=.8

HanAkoSolo (jamierox4ev3r):

Hint: (no need to divide 28 by 35) 28: (1,2,4,7, 14,28) 35: (1,5,7,35) What is the GREATEST number that you see in these factor lists?

likeabossssssss (likeabossssssss):

7 i think caz both 35 + 28 have a 7 that they can dived by

HanAkoSolo (jamierox4ev3r):

that's right! so: \(\Large\frac{28\div 7}{35\div 7}\)

HanAkoSolo (jamierox4ev3r):

and this should give you the ratio that you're looking for

likeabossssssss (likeabossssssss):

` 28/7=4 `

likeabossssssss (likeabossssssss):

` 35/7=5

likeabossssssss (likeabossssssss):

so i was right thank u so much :D

HanAkoSolo (jamierox4ev3r):

yup! I hope this explanation makes sense! ^.^

likeabossssssss (likeabossssssss):

it did

HanAkoSolo (jamierox4ev3r):

But oh! Here's another helpful tip: You actually brought up something helpful earlier. vvvvvvvvvvv When you divide 28 by 35, you get .8 and .8 can also be rewritten as 8/10, which can be simplified to 4/5 because 10 divided by 2 is 5 and 8 divided by 2 is 4.

HanAkoSolo (jamierox4ev3r):

So this could be a faster way to find this, but when you find the greatest common factor, you're sure to find the simpler ratio :)
