Answer 2

Answer:

Step-by-step explanation:

First write down a,b,c as fractions

a = 5/10

b = 2/10

c = 3/10

The denominator is 10 by adding the ratios 5,2,3

Now let’s get down to the question and substitute

(a+b+c)/5a

(5/10 + 2/10 + 3/10) / 5 * (5/10)

When you simplify the numerator you get 1

Therefore

1 / 5*(5/10)

You can take the denominator of the denominator i.e (5/10) to the place of the numerator

Make sure to invert the denominator

(10/5) / 5

Simplify the above and you get 2/5
