A piano teacher has 4\dfrac124 2 1 4, start fraction, 1, divided by, 2, end fraction hours available to teach in a night. Each lesson will last 1\dfrac121 2 1 1, start fraction, 1, divided by, 2, end fraction hours. How many lessons can the teacher schedule in a night?

3 lessons

Step-by-step explanation:

Given

Required

Determine the number of lessons

This is calculated by dividing total hours by time for each lesson.

Convert to improper number

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
