Question 395977: PLEASE HELP ME TO SOLVE AND UNDERSTAND THE FOLLOWING PROPORTIONS;SOLVE FOR X IN THE FOLLOWING PROPORTIONS 3OVERX =20OVER7 AND 7OVER12=XOVER30. THANK YOU MUCH FOR YOUR HELP, I AM STUMPED AND DO NOT UNDERSTAND Answer by solver91311(24713) (Show Source):
Just cross-multiply. The numerator of the right-hand fraction times the denominator of the left hand fraction is equal to the denominator of the right-hand fraction times the numerator of the left-hand fraction. Then divide both sides by the coefficient on x.
And stop typing in all caps. It is the equivalent of shouting and is therefore both annoying and rude.
