Work Step by Step

$\frac{4}{3}$(-6y) We use the Distributive Property to distribute the $\frac{4}{3}$ to all the variables in the parenthesis (-6y). $\frac{4}{3}$$\times$-$\frac{6}{1}$$\times$y We write -6 as -$\frac{6}{1}$ since 6 divided by 1 is still 6 to create a fraction. -$\frac{24}{3}$$\times$y We multiply the fractions together [numerator times numerator over denominator times denominator]. -8$\times$y We can simplify the -$\frac{24}{3}$ to -8 since 24 divided by 3 is 8. The negative cannot be removed since there is no other negative to cancel it out. The answer cannot be further simplified. -8y
