Mathematics

$\frac{191}{60} kg$ o 3.18 kg

Step-by-step explanation:

1. ENCUENTRA UN DENOMINADOR COMUN

Los denominadores que nos dan son: 4, 2, 5, y 3

Encuentra un numero que es comun cuando multiplicas, seria 60.

2. MULTIPLICA EL NOMINADOR POR LO QUE MULTIPLICASTE EL DOMINADOR

Carne= $\frac{7}{4} kg=\frac{105}{60} kg$

Arroz= $\frac{1}{2} kg=\frac{30}{60} kg$

Fruta= $\frac{3}{5} kg=\frac{36}{60} kg$

Papa= $\frac{1}{3} kg= \frac{20}{60} kg$

3. SUMA LAS FRACIONES

Ahora que tienen el mismo denominador, puedes sumar las fraciones

$\frac{105}{60} kg+\frac{30}{60} kg+\frac{36}{60} kg+\frac{20}{60} kg= \frac{191}{60} kg$ o 3.18 kg
