I can't tell you the answers cause that's cheating but I can explain how to do it. Let's use number 1 for an example. It says 1/2 x 2 1/3. First what we want to do is turn all mixed numbers into fractions. So how to do that is take the whole number, in this case 2, and multiply it by the denominator, which in this case is 3. The answer you will get is 6. Then you have to add the numerator onto that, which means 6 + 1 = 7. So now the equation is 1/2 + 7/3. Now you can just multiply both numerators and denominators, so 1 x 7 and 2 x 3, and you will get 7/6, which can be converted to 1 1/6. Apply this method to any of those problems.
The buyers are telling the seller that $40 per t-shirt is way too much. There are multiple stores I can name that will sell you a t-shirt for five dollars, so it just looks like a bad deal. The buyers are saying that the price needs to go down.
