Answer: 47/8
Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator by the whole number and then add the numerator. Finally, we will put our new number over our old denominator and we have our answer which is 47/8.
Therefore,
can be rewritten as the improper fraction 47/8.
12 1/4 because the original answer is 12 3/12 but you should simplify it to 12 1/4.
To find this out, divide 35 by 60:
35/60 = .583333333333
So 35 is 58.3% of 60.
Hope this helps!
The rate for the first is 1 job / 35 minutes and for the second is 1 job / 15 minutes. So combined we get
r = 1/35 + 1/15
3×5×7r = 3 + 7 = 10
r = 10/(105) jobs per minute
We're interested in 1/r
1/r = 105/10 = 10.5 minutes per job
Answer: 10.5 minutes
