"Last month, Carmen paid a gas and electric utility bill of $55. The electricity part of the bill was $20. Write the ratio of the payment for gas to the payment for electricity.
What is the ratio of the payment for gas to the payment for electricity?"
so total (G+E) is (=) 55 G+E=55 E=20 G+20=55 G+20-20=55-20 G=35 G:E 35:20 simplify 35:20 can be thought of as a fraction so 35:20 =35/20 factor out the 5 in each (35=75, 20=45) sp 35/20=5/5 times 5/4 7:4=G:E
