Question

evaluate $\frac{1}{4}xy$ if $x =-\frac{2}{3}$ and $y = 0.6$. write in simplest form.

Explanation:

Step1: Sustituir valores de x e y

Dado $x =-\frac{2}{3}$ y $y = 0.6=\frac{6}{10}=\frac{3}{5}$, sustituimos en $\frac{1}{4}xy$. Tenemos $\frac{1}{4}\times(-\frac{2}{3})\times\frac{3}{5}$.

Step2: Multiplicar fracciones

$\frac{1}{4}\times(-\frac{2}{3})\times\frac{3}{5}=\frac{1\times(- 2)\times3}{4\times3\times5}$.

Step3: Simplificar la fracción

$\frac{1\times(- 2)\times3}{4\times3\times5}=\frac{- 2}{20}=-\frac{1}{10}=-0.1$.

Answer:

$-0.1$
