Step-by-step explanation:
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}
y
2
=
30
12
=> \frac{y}{2} = \frac{30}{12}
2
y
=
12
30
(Taking reciprocal on both sides)
=> y = \frac{30(2)}{12}y=
12
30(2)
(Shifting 2 to RHS)
=> y = \frac{60}{12} = 5y=
12
60
=5
Hence, the value of y = 5
Therefore the correct option is (C) 5
ok!
