Question

Which of these is the most reasonable estimate for how many more hours Mina spent playing the piano last week than Ling? O between 1 and 2 hours O between 2 and 2 hours O between 2 and 3 hours O between 3 and 3 hours​

Answer 1

Answer: between 2 and 3 hours

Explanation:

Easiest method is to convert mixed fractions to decimals:

1-2/3 = 1.67

4-3/10 = 4.3

Ming hrs - Ling hrs = 4.3 - 1.67 = 2.63 hrs

2 < 2.63 < 3
