Question

by what number should we multiple -17/21so that the product may be 51/21​

Answer 1

Hello

Solution :

Let the no.be x

$\frac{ - 17}{21} \times x = \frac{51}{21}$

$x = \frac{51}{21} \div \frac{ - 17}{21}$

$x = \frac{51}{21} \times \frac{ - 21}{ 17}$

$x = \frac{ - 51}{17}$

Verification:

$\frac{ - 17}{21} \times \frac{ -5 1}{17}$

$\frac{51}{21}$

Hope this helps

Answer 2

Step-by-step explanation:

let x is the number which multiple by -17/21 to get 51/21

$\frac{ - 17}{21} \times x = \frac{51}{21} \\ \frac{ - 17x}{21} = \frac{51}{21} \\ - 17x = 51 \\ x = \frac{ - 51}{17} \\ x = - 3$
