Question 1.

Is 10% of a day longer than 1% of a week? Create such questions and challenge your peers. Class 8

Solution:

10% of a day = [latex]\frac{10}{100}[/latex] × 1 = [latex]\frac{1}{10}[/latex] day

1% of a week = [latex]\frac{1}{100}[/latex] × 7 = [latex]\frac{7}{100}[/latex] day

Now, [latex]\frac{1}{10}[/latex] = [latex]\frac{10}{100}[/latex] > [latex]\frac{7}{100}[/latex].

So, 10% of a day is longer than 1% of a week.

Question 2.

Mariam’s farm has a peculiar bull. One day she gave the bull 2 units of fodder and the bull ate 1 unit. The next day, she gave the bull 3 units of fodder and the bull ate 2 units. The day after, she gave the bull 4 units and the bull ate 3 units. This continued, and on the 99th day she gave the bull 100 units and the bull ate 99 units. Represent these quantities as percentages. This task can be distributed among the class. What do you observe? Class 8

Solution:

1 unit out of 2 units

= [latex]\frac{1}{2}[/latex] = [latex]\frac{1}{2}[/latex] × 100 = 50%,

2 units out of 3 units = [latex]\frac{2}{3}[/latex] = [latex]\frac{2}{3}[/latex] × 100 = [latex]\frac{200}{3}[/latex] %

3 units out of 4 units = [latex]\frac{3}{4}[/latex] = [latex]\frac{3}{4}[/latex] × 100 = 75%

4 units out of 5 units = [latex]\frac{4}{5}[/latex] = [latex]\frac{4}{5}[/latex] × 100 = 80%

99 units out of 100 units = [latex]\frac{99}{100}[/latex] = 99%.

Note : Do as directed.
