Step-by-step explanation:
To subtract, you must first:
Find like denominators.
- Note: What you do to the denominator, you must do to the numerator.
- If there is an equal sign, and there are fractions on both side, what you do to one side, you do to the other.
Simplify:
-----------------------------------------------------------------------------------------
Take for example, a question such as:
7 3/10 - 9/20
First, change the mixed fraction into improper fraction:
7 = (7/1) * (10/10) = 70/10 + 3/10 = 73/10
Find common denominators. Remember that what you do to the denominator, you do to the numerator. Multiply 2 to both numerator and denominator:
(73/10)(2/2) = (146/20)
Simplify. Combine like terms
146/20 - 9/20 = 137/20
Simplify.
137/20 = 6 17/20
6 17/20 would be your answer for the example question.

Step-by-step explanation:
Answer:
p = - 
Step-by-step explanation:
Given
p =
( factorise numerator and denominator )
x² - y² ← is a difference of squares and factors as (x - y)(x + y)
x² + xy ← factor out x from each term
= x(x + y) , thus
p =
← cancel (x + y) on numerator/ denominator
=
← substitute x = - 4, y = - 6
= 
= 
=
= - 
Answer:
The length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.
Step-by-step explanation:
Since the length of a rectangle is 5 times the width, to determine the length of the rectangle if the area is 500 square feet, the following calculation must be performed:
Area = Base x height
500 = X x 5X
500/5 = X x X
100 = X x X
100 = 10 x 10
X = 10
Thus, the length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.
