Question 2(f)

Write True (T) or False (F) against the following statement:

$0.9:0.36::10:4$

Answer 1

If two ratios are equal, we say that they are in proportion and use the symbol ‘::’ or ‘=’ to equate the two ratios.

Ratio of 0.9 to 0.36 = $\frac{0.9}{0.36}$ = 10 : 4 = 5:2

Ratio of 10 to 4 = $\frac{10}{4}$ = 10 : 4 =5:2

Since, 0.9 : 0.36 = 10 : 4

Therefore, 0.9, 0.36, 10, 4 are in proportion.

Hence, it is true.
