Answer: 2/35
Step-by-step explanation: First you have to find the minimun common multiplier (MCM). 5 and 7 are prime numbers (only divisible by one and themselves), so they MCM is the product of both, resulting in 5 times 7 equals 35. Now you find the equavilent equation to 1/7 and 1/5 to make them in 5/35 and 7/35, respectively. Finally the clear difference is 2/35. (7/35 - 5/35)

Answer:
82 minutes.
Step-by-step explanation:
So first calculate the percentage 37 minutes is. It is 45%
Next find how much 1% is.
Divide by 45.
![\frac{37}{45}](https://tex.z-dn.net/?f=%5Cfrac%7B37%7D%7B45%7D)
Multiply by 100 to find how much the whole time is: ![\frac{3700}{45}](https://tex.z-dn.net/?f=%5Cfrac%7B3700%7D%7B45%7D)
The decimal version is: 82.2222222222...
Which simplifies to 82 minutes.
There are two possible answers: 72 and 90.
We can find the answer by looking at the largest number among the three of them: 18. The only multiples of 18 between 61 and 107 are 72 and 90. We can check that both numbers are also multiples of 6 and 9:
90 : 6 = 15
90 : 9 = 10
72 : 6 = 12
72 : 9 = 8
