Yikes mctugg brought 1/2 pound of potatoe salad. He ate 2/3 of it for lunch. How much potatoe salad was left for an afternoon snack?

Answer 1

To find out how much potato salad was left after Mctugg ate 2/3 of it, we start with the total amount of potato salad he brought, which is 1/2 pound.

First, we need to calculate how much potato salad he ate: $$\text{Amount eaten}=\frac{2}{3}\times \frac{1}{2}$$

To multiply these fractions, we multiply the numerators together and the denominators together: $$\text{Amount eaten}=\frac{2\times 1}{3\times 2}=\frac{2}{6}=\frac{1}{3}\text{ pound}$$

Now, we can find out how much potato salad is left: $$\text{Amount left}=\text{Total amount}-\text{Amount eaten}$$ $$\text{Amount left}=\frac{1}{2}-\frac{1}{3}$$

To subtract these fractions, we first need a common denominator. The least common denominator of 2 and 3 is 6. We convert the fractions: $$\frac{1}{2}=\frac{3}{6}$$ $$\frac{1}{3}=\frac{2}{6}$$

Now, we can subtract them: $$\text{Amount left}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}\text{ pound}$$

So, there was $\frac{1}{6}$ pound of potato salad left for an afternoon snack.
