Question

Are the ratios 25/45 and 15/27 proportional? explain. I was trying to cross multiply can you please let me know what it is! Or at least how to!

Thanks

Answer 1

If a/b = c/d, then a*d = b*c

If these are proportional, 25/45 and 15/27, then

25/45 15/27, then 25*27 has to equal 45*15

Crank out the multiplications and see if they are proportional.
