Answer 2

The blank space = 18

The above options are wrong

GIVEN:-

$6:12::9:___$

TO FIND:- The blank

SOLUTION:-

• A ratio is the comparison of two or more quantities of the same kind using division. It is denoted as a: b which means $\frac{a}{b}$
• Four numbers are said to be in Proportion if the ratio of the first two is equal to the ratio of the last, i.e., a, b, c and d are said to be in proportion, if a : b::c : d also $\frac{a}{b} = \frac{c}{d}$

According to the question,

Let the blank be x

a = 6; b= 12; c = 9 and d = x

$\frac{a}{b} = \frac{c}{d} \\ \frac{6}{12} = \frac{9}{x}$

By cross multiplying

$6 \times x = 9 \times 12 \\ 6x = 108$

When we shift the number from one side to another the sign changes.

$x = \frac{108}{6} \\ x = 18$

Hence, the blank space = 18
