Question

Si una papaya pesa 6 1/2 kg y una piña 1 3/4 kg ¿Que diferencia de peso tienen?

Answer 1

papaya=6•1/2= 3 Kg
piña= 1•3/4=3/4 Kg

3 Kg-3/4 Kg= 2.25 Kg

Answer 2

6 1/2 = 6 + (1/2) = (12/2) + (1/2) = 13/2
1 3/4 = 1 + (3/4) = (4/4) + (3/4) = 7/4
(13/2) - (7/4) = (26/4) - (7/4) = (26-7)/4 = 19/4
19/4 = (16/4) + (3/4) = 4 + (3/4) = 4 3/4

Respuesta:
4 3/4 kg
