Ayúdenme con este ejercicio 30/4-12/3×(2/5+3/8)

Vamos paso a paso:\frac{30}{4}-\frac{12}{3}\times\left(\frac{2}{5}+\frac{3}{8}\right)1. Paréntesis:\frac{2}{5}+\frac{3}{8}=\frac{16}{40}+\frac{15}{40}=\frac{31}{40}2. Multiplicación:\frac{12}{3}\times\frac{31}{40}=4\times\frac{31}{40}=\frac{124}{40}=\frac{31}{10}3. Resta:\frac{30}{4}-\frac{31}{10}=\frac{15}{2}-\frac{31}{10}=\frac{75}{10}-\frac{31}{10}=\frac{44}{10}=\frac{22}{5}Resultado: (equivale a ).
