Question

Question 2(b)

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

$21:6::35:10$

Answer 1

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

Ratio of 21 to 6 = $\frac{21}{6}$ = 7 : 2

Ratio of 35 to 10 = $\frac{35}{10}$ = 7 : 2

Since, 21 : 6 = 35 : 10

Therefore, 21, 6, 35, 10 are in proportion.

Hence, it is True.
