A shopkeeper has 65 oranges and 39 apples. He sells 28 oranges and 12 apples. How many oranges and apples are left? Express each number as tens and ones.
Answer
Oranges: 3 tens and 7 ones; Apples: 2 tens and 7 ones
The correct answer is Oranges: 3 tens and 7 ones; Apples: 2 tens and 7 ones — Thus the shopkeeper has 3 tens and 7 ones oranges and 2 tens and 7 ones apples left.
Step-by-step solution
- Subtract the number of oranges sold from the total oranges: 65−28=37.
- Express 37 as tens and ones: 3 tens and 7 ones.
- Subtract the number of apples sold from the total apples: 39−12=27.
- Express 27 as tens and ones: 2 tens and 7 ones.
- Thus the shopkeeper has 3 tens and 7 ones oranges and 2 tens and 7 ones apples left.
