Question

The product of 2 number is - 13. If one of the number is -65/7, find the other.​

Answer 1

Answer:

7/5

Step-by-step explanation:

let us consider 2 numbers as X,Y

as per question, product is -13

so,. X*Y =-13

and one number is -65/7. so let Y = -65/7

X * (-65/7) = -13

X = -13*(-7/65)x

X =7/5. ( as 13 x5 = 65 and - x - = +)

$\sf{Product = -13, Given \: number = \frac{ - 65}{7} }$

$\sf \therefore The \: other \: number = - 13 \: \div \: ( \frac{ - 65}{7} )$

$\sf = - \cancel{13} \: \times \frac{7}{ - \cancel{65}}$

$\sf{ = \frac{7}{5} = 1 \frac{2}{5} }.$
