Question 2(c)
Write True (T) or False (F) against each of the following statements:
12:18::28:12
If two ratios are equal, we say that they are in proportion.
Ratio of 12 to 18 = 1218 = 2 : 3
Ratio of 28 to 12 = 2812 = 7 : 3
Since, 12 : 18 ≠ 28 : 12
Therefore, 12, 18, 28, 12 are not in proportion.
Hence, it is False.
