An apple weighs 175 g. If a farmer picks 15 kg of apples in a day, how many apples does he pick.
The mass of each apple is 175 g. To determine the number of apples that weigh X g, divide X by 175. 175 g is equivalent to 0.175 kg.
If a farmer picks 15 kg of apples in a day, the number of apples picked by him is equal to 15/0.175 = 15000/175 `~~` 86.
The farmer picks 86 apples in a day.
