(1 point)
The price for gas is $3.399 per gallon.
To write the price strictly as a decimal, we need to convert the fraction 9/10 into a decimal number.
To do that, we divide the numerator (9) by the denominator (10):
9 ÷ 10 = 0.9
Therefore, the fraction 9/10 can be written as a decimal as 0.9.
Now, we can write the price of gas per gallon strictly as a decimal:
$3.39 + 0.9 = $3.39 + $0.9 = $4.29
So, a gallon of gas costs $4.29.
To convert a mixed number like $3.39 9/10 into a decimal, you can follow these steps:
1. Convert the fraction 9/10 into a decimal. To do this, divide the numerator (9) by the denominator (10):
9 ÷ 10 = 0.9
2. Add the decimal obtained in step 1 to the whole number. In this case, the whole number is 3.39:
3.39 + 0.9 = 4.29
Therefore, the price per gallon, written strictly as a decimal, is $4.29.
