To find 4 out of 10 shaded, we can turn this into a decimal by simply dividing 4 by 10. A rule that many people use is that for every 0 in a 1 with a number of 0’s after it (note that it cannot contain any other numbers), you move the decimal place one to the left. For this, we have 4=4.0 as the decimal is always to the right of the integer. Next, we move the decimal one spot to the left, making our new decimal (and the final answer) 0.40. Unfortunately, however, this is not one of the answers that are possible - I would suggest making sure that 4 out of 10 are indeed shaded (are there 10 out of 10 shaded on the side?) and asking your teacher why 0.4 is not one of the answers.

Answer:
6227020800
Step-by-step explanation:
There are 13 ways to choose the first person in the first group, 12 ways to choose the second person in the first group and so on until we get 1 way to choose the second person in the last group so the answer is 13 * 12 * 11 * ... * 3 * 2 * 1 = 13! = 6227020800.
Jessica is baking cookies for a bake sale and needed 3/4 cups of flower in the original recipe. Jessica's mom later found out that there wouldn't be as many guests so Jessica cut the recipe in half and needs half of the original amount of flour. Jessica now needs 3/8 cups of flour.
Answer:
Its to multiply the numerators by each other and the denominators by each other
Step-by-step explanation:
If adding and subtracting fractions is about finding the least common denominator
dividing fractions is to keep the first fraction,multiply and reverse the second fraction,so dividing is pretty similar to multiplying but just switching the divide sign with a multiplication sign and reversing the second fraction from numerator/denominator to denominator/numerator
and there is always a big difference if you multiply/divide or add/subtract
