11/9 * 27/55
First, you need to transform this expression to one fraction, by multiplying the numerators between each other and put the answer as one numerator, then the denominators and put the answer as one denominator.
11/9 * 27/55 = 297/495.
Now comes the simplifying. You need to divide both numerator and denominator by the same number, till you get an irreducible fraction (a fraction In which numerator and denominator can't be divided by the same number to get another whole number).
In this case, both 297 and 495 are divisible by 99.
297/99 = 3 and 495/99 = 5.
So 297/495 = 3/5.
3 and 5 can't be divided by a same number, so 3/5 represents the irreducible and simplified fraction.
You can re-check your answer (very important):
11/9 * 27/55 = 0.6
297/495 = 0.6
3/5 = 0.6
11/9*22/55 = 297/495 = 3/5
The answer has been approved.
Hope this Helps! :)
Store pays ($3)
Store sells it for ($5.70)
The percent is always (100%) when there selling it.
markup= $3 ÷ $5.70 · 100% = 1.9
Step-by-step explanation
Amount invested = $500
Interest rate = 8%
Duration = 4 years
Therefore total compounded amount after each =
500/100 x 8/1
= 5 x 8 = 40
Multiply by duration of 4 years
= 40 x 4 = $160
Round to nearest Cent
= 100 cents = $1
Therefore $160 = 100 cents x 160
= 16, 000 Cents
Original Price: $45
Current price: 45 x 20% - 45
45 x 20% = 9
Always add/subtract by the original number, but since we're finding the price 'decrease', you subtract by the original number.
45 - 9 = 36
Answer: $36
(5p-1)/3 = 7
⇒ 5p - 1 = 7*3
⇒ 5p -1= 21
⇒ 5p= 21+ 1
⇒ 5p= 22
⇒ p= 22/5
⇒ p= 4 2/5
The final answer is p= 4 2/5~
