Answer:
It will take the apprentice 24 days working alone
Step-by-step explanation:
Let the number of days it takes the apprentice be x
It will take the landscaper x/3 ( since he is three times faster)
The rate for both will be 60/6 = 10 sq m per day
Rate for apprentice is 60/x
rate for the boss is 60/x/3 = 180/x
Adding the rates together;
60/x + 180/x = 10
240/x = 10
240 = 10x
x = 240/10
x = 24 days
Pull out a 5 from the first parenthesis
(5x+15) = 5(x+3)
Pull out a 25 from the second parenthesis
(25x+75) = 25(x+3)
(5x+15) + (25x+75) = your first answer = 5(x+3) + 25(x+3)
Answer:
4 13/33
Step-by-step explanation
If a decimal is repeating, then the fraction would be the repeating number (in this case, 39) over the largest "nine number." If the repeating decimal was only .3 repeating then the fraction would be 3/9. If the fraction was .789 repeating, then the fraction would be 784/999. My teacher used to call this the "nine rule" but that isn't the actual name, so don't call it that. It is a nice way of remembering it though. Also, don't forget the whole number. because the .39 is repeating, that would be 39/99 as a fraction and then the whole number 4 in front of it - 4 39/99. also don't forget to simplify the fraction when you can. In this case, you can simplify 39/99 into 13/33 so the correct answer is 4 13/33.
