Question

If the numerator of an expression is the sum of p, q and r and
the denominator of the expression is the sum of 3p, 3q and 3r;
the expression reduces to
A
1/3
B
1/9
С
1/27
D
1/3pqr

Answer 1

Explanation:

The given rational number will be

$\mathsf{\frac{p+q+r}{3p+3q+3r}=\frac{1(p+q+r)}{3(p+q+r)}=\frac{1}{3}}$

Hence, the expression reduces to 1/3.

Answer: A. 1/3

I hope this helps. :D

Answer 2

The correct answer is option A.

Given: Numerator of an expression is the sum of p, q and r.

Denominator of an expression is the sum of 3p, 3q and 3r.

To Find: The value of expression.

Solution:

Numerator = p+q+r

Denominator = 3p+3q+3r

$\frac{Numerator}{Denominator}=\frac{p+q+r}{3p+3q+3r}$

= $\frac{p+q+r}{3(p+q+r)}$

= $\frac{1}{3}$

Hence, the expression reduces to $\frac{1}{3}$.
