Harriet has enoughgas to make the trip to her friend's house and back without needing to refuel her car.
A fraction represents a part of a whole.
Given that Harriet has 3/4 tank of gas left in her car.
She needs 1/4 tank to go to her friends house and another 1/4 tank to get back home.
We need to check whether she has enough gas for her trip.
Since Harriet has 3/4 of a tank of gas left, she has 1/4 of a tank already used.
She needs another 1/4 of a tank to go to her friend's house and another 1/4 of a tank to get back home.
Altogether, she needs 1/4 + 1/4 = 1/2 of a tank for the round trip.
Hence, Harriet has enoughgas to make the trip to her friend's house and back without needing to refuel her car.

C 3,9 and 2,6
D 3,6 and 2,9 ?
These are the sort of ambiguous word problems 4th graders are exposed to on a daily basis. As the gentleman mentioned, the teacher expects 15, the largest common factor but 1 on each rack fits as well. It should have read “what’s the maximum number of the same item can he/she place on the racks?”
Applying the definition of quotient and creating an equation, the value of the unknown number is: z = 2.
Quotient is the result you get when two numbers are divided with each other.
Thus:
Unknown number = z
Sum of z and 22 is: z + 22
(z + 22)/z = 12 (quotient)
Solve to find the value of z
z + 22 = 12z
22 = 12z - z
22 = 11z
22/11 = z
z = 2
Therefore, applying the definition of quotient and creating an equation, the value of the unknown number is: z = 2.

b) Now use the Distributive Property to write an equivalent expression without parentheses. (You may use the numbers more than once or use different digits for this part only)
Answer:
Mathematical expressions are expressions that uses at least one mathematical operator
(a) The expression
Only one expression fits the given description.
And the expression is (7+5)x6+3
(b) Equivalent expression of (a)
In (a), we have:
Distribute the expression as follows:
Evaluate the products
Hence, the equivalent expression is 42 + 30 + 3
