Answer 1

Answer:

Step-by-step explanation:

1) 2 - (- 8) = 2 + 8 = 10

2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5

3) We can find the common denominators through the least common multiple between the denominators:

4,12 | 2

2, 6 | 2

1, 3 | 3

1, 1 (2 × 2 × 3 = 12)

Then, 12 is the least common denominator.

4) 8 (1/4) + 10 (2/5) + 7 (5/8)

8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4

10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5

7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8

+ 8/8 + 8/8 + 5/8 = 61/8

33/4 + 52/5 + 61/8

Employing the least common denominator:

4, 5, 8 | 2

2, 5, 4 | 2

1, 5, 2 | 2

1, 5, 1 | 5

1, 1, 1 (2 × 2 × 2 × 5 = 40)

(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40

330/40 + 416/40 + 305/40

1051/40

This person ran about 26 Miles
