Question

8) The sum of three
consecutive multiples of 5
is 45. Which is the smallest
of 3 multiples
10
25
15
20​

Answer 1

Step-by-step explanation:

$\huge\mathfrak\blue{Answer;}$

Let us assume that 3 consecutive multiple are x, x+5, x+10

Now,

$x + x + 5 + x + 10 = 45$

$3x + 15 = 45$

$3x = 45 - 15$

$3x = 30$

$x = \frac{30}{3}$

$x = 10$

1 st multiple=10

2 nd multiple=10+5=15

3 rd multiple=10+10=20

therefore,

the smallest multiple is 10.
