d. 4 divided by 2/5 = ?
e. ? divided by 2/5 = 42.

Answer 1

The customer bought 10 bags of tangerines.

Step-by-step explanation:

To find out how many bags of tangerines the customer bought, we need to divide the total weight of tangerines by the weight of each bag. The customer bought 4 kg of tangerines. Each bag weighs 2/5 kg. So, we set up the equation: 4 kg ÷ 2/5 kg = ?

To solve this equation, we need to divide 4 by 2/5. Dividing a number by a fraction is the same as multiplying it by the reciprocal of the fraction. So, 4 ÷ 2/5 is the same as 4 × 5/2. Multiplying 4 by 5 gives us 20 and dividing it by 2 gives us 10. Therefore, the customer bought 10 bags of tangerines.
