Bob had one pound of chocolate chips. he used 1/2 a pound to make cake. he used 1/3 of a pound to make cookies. how much chocolate chips does bob have now?

Bob has 1/6 pound of chocolate chips left. To find this answer, you can't add 1/2 and 1/3 together, so you will have to find an equivalent fraction. Let's start with 1/2. To convert the two fractions into two equivalent fractions with the same denominator, find a number that can be multiplied by 2 to get a number that you can also reach by doing 3 times _. For example, 3. 3x2 can be done to get a denominator of 6. But whatever you multiply by the denominator, you also have to do to the numerator. 3x1 equals 3. So, 3/6 is equivalent to 1/2. Next, you have the fraction 1/3. Because we already found the denominator of 6, we have to find a number that 3 can be multiplied by to get 6. 2, can be multiplied to get 6. But whatever you do to the denominator, you have to do to the numerator. 1x2 equals 2. Then, add the denominator 6. Now you have the numbers 3/6 and 2/6. Add those together to get 5/6. And finally, subtract 1 pound, or 6/6 by 5/6 to get an answer of 1/6. Hope this helped!

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
