Question

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.
