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?
To write the price of gas strictly as a decimal, we need to convert the fraction 9/10 into decimal form.
To do this, we divide 9 by 10:
9 ÷ 10 = 0.9
So, 9/10 can be written as 0.9.
Now, we can write the price of gas per gallon as a decimal:
$3.39 + 0.9 = $3.399
Therefore, a gallon of gas costs $3.399 when written strictly as a decimal.
