There were 50 children at a party. Each child received a packet of sweets which had a mass of 0.15kg. What was the total mass of the sweets that was given out?

To find the total mass of the sweets given out, we need to multiply the mass of each packet by the total number of packets given:

Total mass = 0.15kg/packet x 50 packets
Total mass = 7.5kg

Therefore, the total mass of the sweets given out was 7.5kg.

To calculate the total mass of the sweets that was given out, we need to multiply the mass of each packet of sweets by the number of children at the party.

Given:
Number of children = 50
Mass of each packet of sweets = 0.15 kg

Step 1: Multiply the number of children by the mass of each packet of sweets.
50 children * 0.15 kg = 7.5 kg

The total mass of the sweets that was given out is 7.5 kg.
