I did 2/27 which equals 0.074
So its basically 74
So to make it a percentage we need to move it 2 spaces=
7.4%

Question
Claire’s mother is 4 years more than twice Claire’s age. The sum of their ages is 58 years.
Solution 1
Claire's age = x

claire's mothers age = 2x+4 ( 4 more than twice claire's age)

x + 2x+4 = 58

add like terms ( x +2x = 3x)

3x +4 = 58

subtract 4 from each side:

3x = 54

divide both sides by 3
x = 54 /3
x = 18

Claire is 18 years old
Claire's mother is  2*18 = 36 +4 = 40 years old

Solution 2
Let x = Claire's age
Claire’s mother is 4 years more than twice Claire’s age = 2x + 4
The sum of their ages is 58 years:
x + 2x + 4 = 58
3x + 4 = 58
3x = 54
x = 18

Claire's age = 18
Claire’s mother = 2(18)+4 = 36 + 4 = 40
Question
What two prime numbers equal 85 when added together?
Solution 1

I started out trying to subtract a prime number from 85, and then
see whether I had a prime number remaining.  I did this several
times, before I slapped myself upside the head.

-- 85 is an odd number.

-- To get an odd-number for a sum, you have to add one odd number
to one even number ... there's no other way.

-- So one of the prime numbers we're looking for must be
an even number.

-- The ONLY even number that's a prime number is ' 2 '.
So it must be one of them.

-- Subtract 2 from 85, and you have 83 left.
Is 83 a prime number ?  Yes.

-- So the two numbers are  2  and  83.

If 83 were not a prime number, this wouldn't work, and I would have said
"There is no such pair of numbers.".  That means it doesn't necessarily work
for every odd number.

Examples:

75  ===>  2 and 73 . \
55  ===>  2 and 53 .  \
45  ===>  2 and 43 .   \
Both primes.  It works.

65  ===>  2 and 63 .  63 is not a prime. \
35  ===>  2 and 33 .  33 in not a prime.  \
It doesn't work.

Question
A flagpole casts a showdown 15 feet long the 6 foot tall man casts a shadow 4 feet long how tall is the flag pole
Solution 1
Set it up as a ratio:
mans shadow over mans height (4/6 ) equals flag pole shadow over flag pole height (15/x)

set them to equal each other:

4/6 = 15/x

cross multiply: 4*x =4x, 15*6 = 90

so you have 4x = 90

now divide both sides by 5 to solve for x, which is the height of the flag pole:

x = 90 / 4 = 22.5 feet tall
