Answer:
13/3 or 4 1/3
Step-by-step explanation:
First you convert your mixed numbers into improper fractions:
5/3 × 13/5
You can reduce these fractions by the greatest common factor of 5
1/3 × 13
Multiply
1/3 × 13 = 13/3 or 4 1/3
For the first 60 positive integers, a = 1, n = 60, l = 60.
Sn = n/2(a + l)
s = 60/2(1 + 60) = 30(61)
For the next 60 positive integer, a = 61, n = 60, l = 120
Sum = 60/2(61 + 120) = 30(61 + 120) = 30(61) + 30(120) = s + 3600
Sum of first 120 positive integers = s + s + 3600 = 2s + 3600
