Question

solve step by step solution​

Answer 1

Answer:

$\frac{-3}{7}=\frac{p}{-28}\quad :\quad p=12$

Step-by-step explanation:

$\frac{-3}{7}=\frac{p}{-28}$

$\mathrm{Switch\:sides}$

$\frac{p}{-28}=\frac{-3}{7}$

$\mathrm{Multiply\:both\:sides\:by\:}-28$

$\frac{p\left(-28\right)}{-28}=\frac{\left(-3\right)\left(-28\right)}{7}$

$\mathrm{Simplify}$

$\mathrm{Simplify\:}\frac{p\left(-28\right)}{-28}:\quad p$

$\mathrm{Simplify\:}\frac{\left(-3\right)\left(-28\right)}{7}$

$\frac{\left(-3\right)\left(-28\right)}{7}$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a$

$=\frac{3\cdot \:28}{7}$

$\mathrm{Multiply\:the\:numbers:}\:3\cdot \:28=84$

$=\frac{84}{7}$

$\mathrm{Divide\:the\:numbers:}\:\frac{84}{7}=12$

$=12$

$\therefore\:p=12$
