An easy way to solve this is to convert 1/8 into a percentage then see from that point.
To turn 1/8 into a percentage, you must first get the decimal form of the fraction. In this case, 1/8 as a decimal is 0.125.
Now that we have the decimal form, we can divide the decimal over 100 (common numerical number to use when dividing) to get the percentage, which should be 12.5%.
Now, our new question is 'what's bigger, 80% or 12.5%?'
The answer is 80%, since it is larger than 12.5%.
It will be 20 after u subtract
I've done the first four questions. Use this method to answer the rest. For an odd number of objects find the cost of one and multiply by how many you are asked to find.

Answer:
a) w(4w-15)
b) w²
c) w(4w -15) = w²
d) w = 5
e) 5 by 5
Step-by-step explanation:
a) If w is the width, and the length is 15 less than 4 times the width, then the length is 4w-15. The area is the product of length and width.
A = w(4w -15)
__
b) If w is the side length, the area of the square is (also) the product of length and width:
A = w²
__
c) Equating the expressions for area, we have ...
w(4w -15) = w²
__
d) we can subtract the right side to get ...
4w² -15w -w² = 0
3w(w -5) = 0
This has solutions w=0 and w=5. Only the positive solution is sensible in this problem.
The side length of the square is 5 units.
__
e) The rectangle is 5 units wide, and 4(5)-15 = 5 units long.
The rectangle and square have the same width and the same area, so the rectangle must be a square.
The inverse of it is the inverse of that & thing u know
. There are two numbers greater than 4 (5 and 6), so the probability would be 
. Dividing the numerator and denominator by 2 will simplify it to 
. There is only one number greater than 5, which is 6. This is already in simplest form.
. There are four numbers greater than 2, which are 3, 4, 5, and 6. This makes the probability 
, which simplifies to
