Question

halla la suma de P + Q, sí:

P = 2/5 + 2 + 1/4 - 3/8

Q = 1/2 - 3/4 + 4/5 + 1​

Answer 1

Respuesta:

$P+Q=\frac{153}{40}$

Explicación paso a paso:

$P = \frac{2}{5}+2+\frac{1}{4}-\frac{3}{8}$

$P=\frac{12}{5}+\frac{1}{4}-\frac{3}{8}$

$P=\frac{53}{20}-\frac{3}{8}$

$P=\frac{91}{40}$

$Q=\frac{1}{2}-\frac{3}{4}+\frac{4}{5}+1$

$Q=-\frac{1}{4}+\frac{4}{5}+1$

$Q=\frac{11}{20}+1$

$Q=\frac{31}{20}$

$P+Q=\frac{91}{40}+\frac{62}{40}$

$P+Q=\frac{91+62}{40}$

$P+Q=\frac{153}{40}$
