We will caluclate the cost per gallon first. Then, we will multiply the new quantity by this cost, so we get the new cost.
As we are told that 6 gallons costs 26.58, we can divide 26.58 by 6 to calculate the cost per gallon. It would be
Now we multiply this quantity by 18, so we get the cost of 18 gallons. It would be
so the cost of 18 gallons is 79.74
Mercury: 87 24/25
Venus 224 7/10
Mars 686 49/50
All we need to do is to convert fractions so they have a denominator of 10, 100, 1000 etc.
87 24/25 = 87 96/100
224 7/10 stays the same
686 49/50 = 686 98/100
Now we can easily convert them into decimals:
Mercury: 87.96
Venus: 224.7
<span>Mars: 686.98</span>
