Question

What is the antecedent term in the simplest form of the ratio 15:25 ?

• A. 15
• B. 5
• C. 3
• D. 25

Answer 1

The correct option is C 3

In the simplest form, the numerator and denominator have no common factors other than 1.
We know, 15 = $3\times 5$ and
25 = $5\times 5$

We can write 15 : 25 as $\frac{15}{25}$
$\therefore$ $\frac{15}{25}$ = $\frac{(3\times 5)}{(5\times 5)}$
$\Rightarrow$ $\frac{3}{5}=3:5$

We know, for a ratio a : b, a is called the antecedent and b is called the consequent.
$\therefore$ In this case, 3 is the antecedent term.
