Claro, vamos a resolver la pregunta paso a paso:

1. Convertir las cantidades de zanahorias, tomates y cebollas a una forma más manejable:

- Zanahorias: [tex]\( \frac{3}{4} \)[/tex] kg
- Tomates: [tex]\( 2 \frac{1}{2} \)[/tex] kg = [tex]\( 2 + \frac{1}{2} = 2.5 \)[/tex] kg
- Cebollas: [tex]\( 1 \frac{2}{5} \)[/tex] kg = [tex]\( 1 + \frac{2}{5} = 1.4 \)[/tex] kg

2. Calcular el peso total de las verduras que Adriana ya ha comprado:

- Peso total = [tex]\( \frac{3}{4} \)[/tex] zanahorias + [tex]\( 2.5 \)[/tex] tomates + [tex]\( 1.4 \)[/tex] cebollas

Convertimos [tex]\( \frac{3}{4} \)[/tex] a decimal para facilitar la suma:

- [tex]\( \frac{3}{4} = 0.75 \)[/tex]

Entonces sumamos:

- Peso total = [tex]\( 0.75 \)[/tex] kg + [tex]\( 2.5 \)[/tex] kg + [tex]\( 1.4 \)[/tex] kg
- Peso total = [tex]\( 4.65 \)[/tex] kg

3. Determinar cuánto le falta comprar para llegar a los 8 kg de la oferta:

- Cantidad necesaria para la oferta = 8 kg
- Peso total comprado = [tex]\( 4.65 \)[/tex] kg

La cantidad de verduras que aún necesita comprar es:

- [tex]\( 8 \)[/tex] kg - [tex]\( 4.65 \)[/tex] kg = [tex]\( 3.35 \)[/tex] kg

Entonces, Adriana necesita comprar [tex]\( 3.35 \)[/tex] kg más de verduras para acceder a la oferta especial.
