5/6-1/8 Solve by finding a common denominator<br><br> A)30/48<br> B)34/48<br> C)38/48<br> D)42/48
GrogVix [38]

Answer:

  B)  34/48

Step-by-step explanation:

The easiest common denominator to find is the product of the denominators you have.

__

The difference is ...

  \dfrac{5}{6}-\dfrac{1}{8}=\dfrac{5}{6}\cdot\dfrac{8}{8}-\dfrac{1}{8}\cdot\dfrac{6}{6}\\\\=\dfrac{40-6}{48}=\boxed{\dfrac{34}{48}}

__

<em>Additional comment</em>

The difference numerator and denominator have a common factor of 2, so can be reduced to 17/24. The denominator 24 could have been used as the common denominator from the start.

  5/6 -1/8 = 20/24 -3/24 = 17/24 . . . . reduced result

__

Using the <em>least common denominator</em> does not always result in a reduced sum or difference. If some other denominator is used (as here), then you can be assured that the result will need to be reduced to get to lowest terms.

Sue had 5 identical bags of candy to share with the crew. Twenty-five pieces of candy disappeared. Ted had 4 bags with the same
inna [77]

Answer:

Each bag originally had 35 pieces of candy

Step-by-step explanation:

Since the bags are identical, Let them Number of candies in each bag sue had be x. Thus, she had 5x candies. Since she lost 25 pieces, then she now has;

5x - 25 candies left.

We are told that Ted had 4 bags with the same number of candies like Sue had. Thus, he has 4x candies.

He mysteriously found 10 additional pieces. Total Ted now has is;. 4x + 10

Finally, we are told that Sue and Ted now have an equal number of candies.

Thus;

5x - 25 = 4x + 10

Rearranging, we have;

5x - 4x = 25 + 10

x = 35

Thus, each bag originally had 35 pieces of candy

Max observes the zoo and the library from a helicopter flying at a height of 400 times square root of 3 feet above the ground, a
-BARSIC- [3]

Answer: First option: 800 feet

Solution:

Height: h=400 sqrt(3)

Distance between the zoo and the point in the ground below the helicopter: d1=?

Distance between the library and the point in the ground below the helicopter: d2=?

Distance between the zoo and the library: d=?

d=d2-d1


tan 60°= h/d1

sqrt(3)=400 sqrt(3) / d1

Solving for d1:

sqrt(3) d1 = 400 sqrt(3)

d1= 400 sqrt(3) / sqrt(3)

d1=400


tan 30°= h/d2

sqrt(3) / 3=400 sqrt(3) / d2

Solving for d2: Cross multiplication:

sqrt(3) d2 = 3 [ 400 sqrt(3) ]

sqrt(3) d2 = 1,200 sqrt(3)

d2= 1,200 sqrt(3) / sqrt(3)

d2=1,200


d=d2-d1

d=1,200 feet - 400 feet

d=800 feet
