2lb, 891g, 1 kg, 0.02 t greatest to least

0.02 T > 1 kg > 2 lb > 891 g.

Step-by-step explanation:

We have given different quantities as: 2 pounds, 891 gram, 1 kilogram, 0.02 Tonnes.

We need to write the given quantities in order from greatest to least.

We know that,

1 pound(lb) = 0.4536 kilogram.

1 gram = 0.001 kilogram.

1 tonne = 1000 kilogram.

We have given different units of different quantities. We can convert the different units of different quantities in a particular unit, say Kilograms(kg). So, we can find the different results by converting the quantities.

2 pounds = 2*0.4536 kilograms = 0.907 kg.

891 gram = 891*0.001 kilograms = 0.891 kg.

0.02 tonne = 0.02*1000 kilograms = 20 kg.

Therefore, the order from greatest to least can be written as: 20 kg > 1 kg  > 0.907 kg > 0.891kg.

Substituting the original units given in problem, the order can be written as:

0.02 T > 1 kg > 2 lb > 891 g.
