Answer: OPTION D: 
Step-by-step explanation:
By definiton, fractions have the following form:

Where "a" is called numerator and "b" is the denominator. The numerator and the denominator are Integers.
In order to solve this exercise you need to remember de Division of fractions:

In this case, according to the information given in the exercise, you know that
of rubies are divided into 4 lots.
Therefore, in order to calculate the weight in pounds of each lot, you need to divide
by 4.
Then, you get the following result:

As you can notice, this result matches with the Option D.
81 because 81 is a perfect square and 27 times 3 =81

Answer:
Option (3)
Step-by-step explanation:
The ramp shown in the figure is in the shape of a triangular prism.
Therefore, total surface area of this ramp = Area of the triangular sides + Area of the base + Area of the vertical side + Area of the slanting side
Area of the triangular sides = ![2[\frac{1}{2}(Base)\times (h)]](https://tex.z-dn.net/?f=2%5B%5Cfrac%7B1%7D%7B2%7D%28Base%29%5Ctimes%20%28h%29%5D)
= bh
= 4×3
= 12 square feet
Area of the rectangular base = Length × Width
= 4 × 8
= 32 square feet
Area of the vertical side = Length × Width
= 3 × 8
= 24 square feet
Area of the slanting side = Length × width
= 8×5
= 40 square feet
Total surface area = 12 + 32 + 24 + 40
= 108 square feet
Option (3) will be the answer.
25/14
According to BODMAS rule. multiplicaion comes first so, 11+14 gives you 25 and this is divided by 14
