When measuring time, 8 concerts are approximately equal to 6 symphonies. How many symphonies are equal to 42 symphonies?
Vinil7 [7]
So normally it is
if 8x is to 6y, then how many x is to 42y?
it could be
if 8x:6y then how many x:42y or
if 8x:6y then how many y:42 x

I will solve for both

if it is
x:42y go to AAAAAAAA
if it is
y:42x then go to BBBBBBBBBB


AAAAAAAA
 how many concerts are equal to 42 symponies
arrange in concerts to symponies format

8:6=x:42
fractionify
8/6=x/42
multiply boht sides by 42
336/6=x
56=x
56 concerts equals 42 symponies



BBBBBBBBBB

 how many  symponies are equal to 42 concerts
areange in symponies:concerts
6:8=x/42
fractionify
6/8=x/42
multiply boht sides by 42
252/8=x
31.5=x
31.5 symponies to 42 concerts




so it could be


56 concerts to 42 symponies
or
31.5 symonies to 42 concerts
