the answer the c:(5)

Answer 2

Answer:

Hey there!

The answer is : (C) 5

Step-by-step explanation:

Given:    2 : y = 12 : 30

Procedure: We can also write it as,  $\frac{2}{y} = \frac{12}{30}$  

                                    => $\frac{y}{2} = \frac{30}{12}$        (Taking reciprocal on both sides)

                                    => $y = \frac{30(2)}{12}$     (Shifting 2 to RHS)

                                    => $y = \frac{60}{12} = 5$  

Hence, the value of y = 5

Therefore the correct option is (C) 5
