They are: 15, 30, 45, 60.
45% is greater than 30/70
The least common multiple of the numbers 30, 70 and 45 is 630.
15, 30, 45, 60
630
The answer is pretty simple. It is 105.I figured it out by doing this:15: 15, 30, 45, 60, 75, 90, 10535: 35, 70, 105
15, 30, 45 and so on. 35, 70, 105 and so on. Common multiples include 105, 210, 315 and so on.
Since there are 2 numbers in the group, the group average is 1/2 of their sum.
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100.
x*(70/100)+y*(30/100)=100*(45/100) .7x+.3y=45 x+y=100 y=100-x .7x+.3(100-x)=45 .7x+30-.3x=45 .4x=15 x=15/.4=37.5 gallons y=100-x=100-37.5=62.5 gallons
70-(30+15)=25
The GCF is 5.
