Question

2:x and 12:18 a-3, b-4, c-6

Answer 1

2/x = 12/18
cross multiply
(12)(x) = (18)(2)
12x = 36
x = 36/12
x = 3

Answer 2

The Corrected Problem is :

2:x and 12:18 identify the value of x that makes each pair of ratios equivalent .

Solution:

If a pair of Ratios are equivalent then we can write

$\frac{2}{x}=\frac{12}{18}\\ \\ \text{Simplify we get}\\ \\ 12x=36\\ \\ \text{Divide both the sides by 12 we get}\ \\ \\ \frac{12x}{12}=\frac{36}{12}\\ \\ x=3\\ \\ \text{Hence the required value of x is 3}$
