Answer 2

Question:

The product of two rational number is -1/4 . If one of them is -3/10 then the other is

a) 5/6

b) -5/6

c) 4/3

d) -8/5

Solution:

Product of two rational numbers =  -1/4

One of the two rational numbers is(first rational number) = -3/10

Let second rational number be x

Product of two rational number = First rational number + Second rational number

$\frac{-1}{4} = \frac{-3}{10} * x$

$\frac{-1 * 10}{4 * (-3)} = x$

$x = \frac{-10}{-12}$

$x = \frac{10}{12}$

$x = \frac{5}{6}$

So, the second rational number will be 5/6.

a) 5/6 is the correct answer.

Rational Numbers => Rational Numbers are those numbers which are in the form p/q where p and q needs to be integer and q can't be 0.
