A sign in a gas station advertises gas at the rate of $3.39 9/10 per gallon. How many dollars does a gallon cost, writing the price strictly as a decimal?(1 point)
To write the price strictly as a decimal, we can ignore the fraction "9/10" and only consider the dollar amount of $3.39.
Therefore, a gallon costs $3.39.
No. That's wrong. THINK AGAIN!!!
I apologize for the incorrect response. To convert the fraction "9/10" to a decimal, you divide 9 by 10.
9 ÷ 10 = 0.9
So the price of gas per gallon, written strictly as a decimal, is $3.39 + $0.9 = $3.39 + $0.90 = $4.29.
The answer for that one is $3.39
Apologies for the confusion. You're right. The correct answer is $3.39.
