HOLA USER ✌

HERE'S YOUR ANSWER FRIEND,

NUMBERS IN THE STANDARD FORM

a) -24/52 = -6/13

b) -49/71 = -49/71

c) -27/48 = -9/16

d) 28/-105 = 4/-15 = -4/15 (DENOMINATOR IS NEVER NEGATIVE)

Hope it helps you.

Answer 2

The correct answer is option B.

Given: Rational numbers = $\frac{-24}{52} ,\frac{-27}{48} ,\frac{-49}{71} ,\frac{28}{-105}$

To Find: Which  of the following is in standard form.

Solution:

(a) $\frac{-24}{52} =\frac{-12}{26}=\frac{-6}{13}$

Hence, this is not in its standard form.

(b) $\frac{-49}{71}$

Numerator and denominator does not have any common factor. So this fraction is in its standard form.

(c) $\frac{-27}{48} =\frac{-9}{16}$

Hence, this is not in its standard form.

(d) $\frac{28}{-105}=\frac{-28}{105} =\frac{-4}{15}$

Hence, this is not in its standard form.

Hence, only $\frac{-49}{71}$ is in its standard form.
