Example Question #21 : How To Divide
Francis baked a cake that weighed 16 ounces. He then cut the cake into 4 equal pieces and gave one piece to his mother. His mother ate half of the piece of cake. How many ounces of cake did she eat?
If Francis baked a cake that weighed 16 ounces and then cut the cake into 4 equal pieces, each piece weighed ounces.
If Francis's mother ate half of the piece of cake, she ate ounces.
Example Question #22 : How To Divide
What is the value of ?
In order to solve , the second fraction must be flipped and multiplied by the first fraction. This gives us:
The numerators are multiplied by one another, as are the denominators. This results in , which is the correct answer.
Example Question #23 : How To Divide
What is the value of ?
is equivalent to , which is equal to .
Therefore, is the correct answer.
Example Question #24 : How To Divide
What is half the product of r and s?
The product of r and s is eqal to . Therefore, half of the product of rs will be equal to rs divided by 2. This results in:
Example Question #25 : How To Divide
Write .8 as a fraction in its simplest form.
The decimal .8 is equal to . When the numerator and denominator are divided by 2, the result is , which is the correct answer.
Example Question #26 : How To Divide
What is 14 divided by 5?
When 14 is divided by 5, the result is 2 with a remainder of 4. This is because 5 times 2 is 10, and 14 minus 10 is 4.
Therefore, the correct answer is .
Example Question #27 : How To Divide
If 17 divided by x is equal to 3 remainder 2, what is the value of x?
A simple way to solve this problem is to plug in one of the answer choices for x. If 5 is plugged in as x, 17 divided by 5 is 3 with a remainder of 2. This is because 5 times 3 equals 15, and 17 minus 15 is equal to 2.
Therefore, 5 is the correct answer.
Example Question #28 : How To Divide
Oliver has a map where 1.5 centimeters represents 2 city blocks. If her house is 7.5 centimeters from the bus stop, what is the distance in city blocks?
One of the ways to solve this problem is to divide 7.5 centimeters by 1.5 centimeters which will tell us how many times we travelled two blocks.
This gives us the answer 5.
This means that Oliver travelled 1.5 centimeters 5 times.
We know that each time he travels 1.5 centimeters, he goes two city blocks, so we can multiply.
city blocks.
Example Question #29 : How To Divide
In order to divide fractions, we first take the reciprocal of the second fraction. To find the reciprocal, we switch the numerator and the denominator. So, the reciprocal of is .
Then we multiply the first fraction and the reciprocal.
We then multiply the numerators together: .
Then we multiply the denominators together: .
We divide the numerator (25) by the denominator (24) to get .
Example Question #30 : How To Divide
When a number is divided by , and the remainder is , which could be the number?
In order to solve this problem, we need to divide our answer choices by , and then see which has a remainder of .
Therefore, is the correct answer for this problem.
