Not a solution I believe.
One is negative and the other is positive and one has a whole number, and the other only has a decimal
Let us start with the time it takes for 1 gallon of gas to be dispensed. If ½ gallon takes 3 ¼ seconds, it will take double of that time for one gallon of gas. Double of 3 <span>¼</span> seconds is 6 1/8 seconds. Unit rate is 1 gallon of gas at every 6 1/8 seconds If one gallon of gas takes 6 1/8 seconds, 50 gallons will take 50 x 6 1/8 seconds. That is, 325 seconds or 5 minutes ans and 25 seconds.
1. 28/15 as a decimal is <span>1.86666666666667
2.
</span><span>the number is divisible by 3. </span>
<span>Additionally, we know 120,000 is divisible by 3, 18,000 is divisible by 3, 420 is divisible by 3, and 15 is divisible by 3.
I hope this helps! I didn't do the last one my friend did but he thinks it's right. Please correct me if wrong.</span>
