Are the ratios 25/45 and 15/27 proportional?
ok to everyone who still doesn't get it
think of those ratios as fractions
when they ask if its proportional, they're asking if those ratios, or fractions, equal the same (for e.g, 3/4 = 36/48)
so you have to find how both of them can turn into the same number so find the common numbers between them!
what number is both 25 and 45 divisible by? 5
25÷5=5, 45÷5=9, or 5/9
what number is both 15 and 27 divisible by? 3
but why not 5?
27÷5 is not rational, therefore it it 3 since 3 can go into 15 and 27
15÷3=5, 27÷3=9, or 5/9
so yes, they are both proportional.
You would not divide them by 5, because that is 5/1. You would divide them by 5/5. BIG DIFFERENCE!!!
Your welcome. Those of you that would have to explain this would get it wrong if you listened to Abcd.
But the answer is yes still.
lun is the next einstein thanks so much lun . You will probably get a nobel prize and be the smartest person alive
:)
Yes because when we smaller them like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
BUT WHATS THE ANWERS IM SOOOO CONFUSED/??????
Its sad how dumb I feel rn but thanks Lun :3

Bro someone could like start writing diary entrances and no one would know who it was, has this happened yet?
For those of you who are still stuck:
25x27=675
15x45=675
Therefore making 5/9
