Answer:

Answer: 17892

Solution:

The multiples of 7 between 0 to 500 are:

7x1 = 7

7x2 = 14

7x3 = 21

7x4 = 28

7x5 = 35

………….

7x70 = 490

7x71 = 497

Therefore total number of multiples of 7 between 0 and 500 are 71. If we denote by S71 the sum of all these multiples,

S71 = 7+14+21+28+35+…………+490+497

= 7(1+2+3+4+………………….+70+71)

The series within parentheses is the sum of the first 71 natural numbers and the sum is given by the formula n(n+1)/2, where n=total number of terms=71 . Substituting for n,

S71 = (7x71x72)/2 = 7x71x36 = 17892 (Answer

Step-by-step explanation:

**Answer:**

1/6

**Step-by-step explanation:**

1 1/4 = 5/4

7 1/2 = 15/2

(5/4) / (15/2) = (5/4) x (2/15)

= 10/60

= 1/6
