Question 2(c)

Write True (T) or False (F) against each of the following statements:

$12:18::28:12$

Answer 1

If two ratios are equal, we say that they are in proportion.

Ratio of 12 to 18 = $\frac{12}{18}$ = 2 : 3

Ratio of 28 to 12 = $\frac{28}{12}$ = 7 : 3

Since, 12 : 18 $\ne$ 28 : 12

Therefore, 12, 18, 28, 12 are not in proportion.

Hence, it is False.
