The mass of 40 packs of biscuits is 6.4kg. Each

pack has 5 biscuits. What is the mass, in grams,
of one biscuit?

To find the mass of one biscuit, we need to divide the total mass of 40 packs of biscuits by the total number of biscuits.

The total number of biscuits is 40 packs * 5 biscuits/pack = 200 biscuits.

The mass of one biscuit is 6.4kg * 1000g/kg / 200 biscuits = 32 grams.

Therefore, the mass of one biscuit is 32 grams.

To find the mass of one biscuit, you need to divide the total mass of 40 packs of biscuits by the total number of biscuits.

Step 1: Convert the mass of the packs from kg to grams.
6.4 kg = 6,400 grams

Step 2: Multiply the number of packs by the number of biscuits per pack.
40 packs * 5 biscuits per pack = 200 biscuits

Step 3: Divide the total mass by the total number of biscuits.
6,400 grams / 200 biscuits = 32 grams

Therefore, the mass of one biscuit is 32 grams.

To find the mass of one biscuit, we can follow these steps:

1. Calculate the total mass of all the packs of biscuits. Given that the mass of 40 packs is 6.4 kg, we can divide the total mass by the number of packs: 6.4 kg / 40 packs = 0.16 kg.

2. Convert the mass from kilograms to grams since the question asks for the mass of one biscuit in grams. There are 1000 grams in one kilogram, so we multiply the mass in kilograms by 1000: 0.16 kg × 1000 = 160 grams.

Therefore, the mass of one biscuit is 160 grams.
