We simply need to find a common denominator. The common denominator between the two (LCM/Least common multiple for denominator) is 24.

Now, we multiply the numerators also. We have our new numbers: 2 8/24 for October, 12/24 for November, and 3 9/24 for December. Now, we have to add them together. 2 8/24 + 12/24 = 2 20/24

Now, add the December value to the combined October/November values.

2 20/24 + 3 9/24 = 5 29/24

Now, we need to simplify the fraction.

6 9/24

Answer: 6 3/8 inches of rain occured in the three months.

Levart [38]

Answer:

Total = 686000 meters for 10 weeks 7 days a week.

Step-by-step explanation:

Let's solve this by doing the increase on just 1 training day per week. Then we can find the grand total for 7 days a week by multiplying by 7

a = 8000

n = 10

d = 400

Sum = (a + L)*n/2

  • L = a + (n - 1)*d
  • L = 8000 + (10 - 1)*400
  • L = 8000 + 9*400
  • L = 8000 + 3600
  • L = 11600 meters

Sum = (8000 + 11600)*10/2

Sum = 19600 * 10/2

Sum = 98000 meters.

This total represents 1 training day a week.

The total amount is 7 times this figure.

Total = 7 * 98000 = 686 000 meters.
