Are the ratios 25/45 and 15/27 proportional? Explain.
it may be rude, but VERY true
I JUST FOUND THE ANSWER
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.
check to see whether
25/45 = 15/27
a/b = c/d if ad=bc
