Question

if [6/15=2/a=10/b]then a and b are respectively _______​

Answer 1

Answer:

a = 5  , b = 25

Step-by-step explanation:

$\frac{6}{15}  = \frac{2}{a}  = \frac{10}{b}$

Finding a

Considering  first two equations only,

We get $\frac{6}{15}  = \frac{2}{a}$

or by cross multiplication of terms, we get  6 (a) = 15 x 2 = 30

or , a = 30/ 6 =  5

So, a = 5

Finding b

Considering  last two equations only,

We get$\frac{2}{a = 5}  = \frac{10}{b}$ 

or by cross multiplication of terms, we get  2 (b) = 10 x 5 = 50

or , b = 50/ 2 =  25

So, b = 25
