Question

a) The product of two rational numbers is -1 if one of the rational number is -17 /8 find the other.
b)The product of two rational numbers is 35/ 126 .If one of them is -9/ 60 ,find the other
​

Answer 1

Answer:

a. 8/17

b. 50/-27

Step-by-step explanation:

-1/-17/8=-8/-17=8/17

35/126/-9/60=50/-27

Answer 2

Answer:

hey

Step-by-step explanation:

Solution 1:

given

The product of two rational number is 1. if one of the rational number is 8/21.

to find

The other number.

explanation

Let the other number be r

A/q

$\frac{8}{21} * r=1\\\\\frac{8r}{21} =1\\\\8r=21\\\\r=\frac{21}{8}$

Thus;

$\frac{21}{8}$ is the other number  

Solution 2:

The product of two rational number is 35/126. if one of the rational number is -9/60.

Let the other number be r

A/q

$\frac{-9}{60}*r=\frac{35}{126} \\\\\frac{-9r}{60} =\frac{35}{126} \\\\-9r*126=35*60\\-1134r=2100\\r=\frac{-2100}{1134} \\\\r=\frac{-350}{189}$

Thus; the other number is -350/189
