Bill ate 1/4 of a pound and then 1/6 of a pound. All together, we can find out how much he ate if we add the fractions. But first, we have to expand them to a common denominator. We can see that a number that is both divisible by 6 and 4 is 12, so we expand until both of their denominators are 12.
1/4 * 3/3 = 3/12 1/6 * 2/2 = 2/12
Now add them, and you get 5/12. In total, Bill ate 5/12 of a pound of trail mix.
B. “Y = 15x” would be your answer. Y is your end balance and x is the weeks. For example, if x is 3 weeks, your equation would be 45 = 15*3. In this case, y would be 45. Need anymore help?
