Answer 1

Problem:

Хозяйка купила 1/2 кг сметаны. Масса банки со сметаной 13/20 кг. Какова масса банки?

Solution:

To find the mass of the jar, we need to subtract the mass of the cream from the total mass of the jar.

Let's start by finding the mass of the cream. The owner bought 1/2 kg of cream.

Next, we need to find the total mass of the jar. The mass of the jar with the cream is 13/20 kg.

To find the mass of the jar, we subtract the mass of the cream from the total mass of the jar:

Mass of the jar = Total mass of the jar - Mass of the cream

Let's calculate it step by step:

1. Convert 1/2 kg to a fraction with a common denominator of 20:

1/2 kg = 10/20 kg

2. Subtract the mass of the cream from the total mass of the jar:

Mass of the jar = 13/20 kg - 10/20 kg

Mass of the jar = (13 - 10)/20 kg

Mass of the jar = 3/20 kg

Therefore, the mass of the jar is 3/20 kg.

Answer:

The mass of the jar is 3/20 kg.
