Working with Fractions Class 7 Very Short Question Answer

Question 1.

Find the value of [latex]\frac {1}{9}[/latex] × 2[latex]\frac {3}{7}[/latex].

Solution:

[latex]\frac {1}{9}[/latex] × 2[latex]\frac {3}{7}[/latex] = [latex]\frac {1}{9}[/latex] × [latex]\frac {17}{7}[/latex]

= [latex]\frac{1 \times 17}{9 \times 7}[/latex] = [latex]\frac {17}{63}[/latex]

Question 2.

Find [latex]\frac {2}{3}[/latex] of 15.

Solution:

[latex]\frac {2}{3}[/latex] of 15 = [latex]\frac {2}{3}[/latex] × 15 = [latex]\frac {30}{3}[/latex] = 10

Question 3.

Find the value of 1[latex]\frac {3}{5}[/latex] ÷ [latex]\frac {1}{2}[/latex].

Solution:

1[latex]\frac {3}{5}[/latex] ÷ [latex]\frac {1}{2}[/latex] = [latex]\frac {8}{5}[/latex] ÷ [latex]\frac {1}{2}[/latex]

= [latex]\frac {8}{5}[/latex] × [latex]\frac {2}{1}[/latex] = [latex]\frac {16}{5}[/latex] = 3[latex]\frac {1}{5}[/latex]

Question 4.

Find the value of [latex]\frac {2}{3}[/latex] × 4[latex]\frac {2}{9}[/latex].

Solution:

[latex]\frac {2}{3}[/latex] × 4[latex]\frac {2}{9}[/latex] = [latex]\frac {2}{3}[/latex] × [latex]\frac {38}{9}[/latex]

= [latex]\frac {76}{77}[/latex] = 2[latex]\frac {22}{27}[/latex]

Question 5.

Find the value of 3[latex]\frac {1}{2}[/latex] ÷ 2[latex]\frac {3}{5}[/latex].

Solution:

3[latex]\frac {1}{2}[/latex] ÷ 2[latex]\frac {3}{5}[/latex] = [latex]\frac {7}{2}[/latex] ÷ [latex]\frac {13}{5}[/latex]

= [latex]\frac {7}{2}[/latex] × [latex]\frac {5}{13}[/latex] = [latex]\frac {35}{26}[/latex] = 1[latex]\frac {9}{26}[/latex].
