Question

2. a:b:c = 2:3:7. a is what % of total (a + b + c)?​

Answer 1

Answer:

a if 16.67% of a + b + c

Step-by-step explanation:

Given that a : b : c = 2 : 3: 7

a = 2x

b = 3x

c= 7x

$\frac{a}{a + b + c} = \frac{2x}{12x} \times 100 = \frac{100}{6}\% = 16.67\%$

Answer 2

Answer:

16.6%

Step-by-step explanation:

a:b:C=2:3:7

let us these ratios as

a=2x, b=3x and c= 7x

sum =12x

percentage of a= a/total sum ×100

2x/12x ×100

=100/6=16.6%
