Answer:
9/2 kg = 4 1/2 kg
Explanation:
You want the mass of 6 toys, each with a mass of 3/4 kg.
Proportional
The total mass is proportional to the number of toys. Six of them will have six times the mass of one of them.
6 × 3/4 = (6×3)/4 = 18/4 = 9/2
The total mass of the toys is 9/2 kg, or 4 1/2 kg. As a decimal, it is 4.5 kg.
