These are all fraction math problems. Lemme walk you through one of them and then you can buckle down and do the rest.

Sheridan has 6 1/3 boxes of charcoal. Each sketch needs 3 2/4 boxes. OK, first, check on the accuracy of the 3 2/4. Maybe you wrote that down wrong. It looks odd to me.

But we need to divide 6 1/3 by 3 2/4. STEP ONE - make them both fractions. 6 1/3 becomes 19/3 (six times three plus one, OK). 3 2/4 becomes 14/4. Now the problem is (19/3)/(14/4). Be generous with parenthesis, they are free and keep things organized.

Now we have some thirds and some fourths, so STEP TWO - get the denominators the same. 3 x 4 (the original denominators) = 12 so 12 would be a good "common denominator" so we multiply top and bottom of each fraction to get them in twelfths. That gives (19x4)/(3x4) = 76/12. Remember when it was 6 1/3? Same number, different form now and one we can use. We will muiltiple 14/4 by three top and bottom to get 42/12. Same as the 3 2/4 we started with, different form. Now, both are in in twelfths and the problem now is: (76/12)/(42/12).

If we multiply the top and bottom by 12, the 12s go away and we have 76/42. Solve that part yourself.

But the pattern is: Take each number and "expand" it to a complete fraction. Then get each so that they have "common" denominatprs (same number on the bottom). Then the math is easy. Remember, a fraction doesn't change its value if you multiply or divide the top and bottom by the same number. Addition and subtaction don't work that way, just multiply and divide. So, the fraction is changed in form only, into something we can get our hands on. The value remains the same.

Question 1.

You need to calculate 2 1/3 divided by 3 1/5. The smallest number divisible by both 3 and 5 is 15.

Multiply both original figures by 15 to arrive at the answer of 35/48.
