Final answer:
The number of mangoes in a 56kg bag when each mango has an average mass of 1⅗ kg (1.6kg) is calculated by dividing the total mass by the average mass of one mango, which yields 35 mangoes.
Step-by-step explanation:
The student asked how many mangoes are in a bag that has a total mass of 56kg, given the average mass of a mango is 1⅗kg. To find the number of mangoes, you need to divide the total mass of the bag by the average mass of one mango.
First, convert the fractional part of the mango's average mass to a decimal. The average mass of a mango is 1 and 3/5 or 1.6 kg in decimal form. Now, you divide the total mass of the bag, 56 kg, by the average mass of one mango, 1.6 kg.
The calculation is as follows:
56 kg ÷ 1.6 kg/mango = 35 mangoes.
Therefore, there are 35 mangoes in the bag.
