Question

by what number should you multiply 2/3as to get -1​

Answer 1

Answer:

๛ Let x be multiplied.

๛ According to the question :

$x \times \frac{2}{3} = - 1 \\ \\ = > \frac{2x}{3} = - 1 \\ \\ = > 2x = - 1 \times 3 \\ \\ = > 2x = - 3 \\ \\ = > x = \frac{ - 3}{2}$

☞ So -3 / 2 should be multiplied by 2 / 3 to get ( - 1 )

☞ Verification of my answer :

$\frac{2}{3} \times \frac{ - 3}{2} \\ \\ = \frac{ - 6}{6} \\ \\ = - 1$
