A Celestial Pearl Danio’s length is 2 4/10 cm, and the length of a Philippine Goby is 9/10 cm. Class 7

A Celestial Pearl Danio’s length is 2[latex]\frac{4}{10}[/latex] cm, and the length of a Philippine Goby is [latex]\frac{9}{10}[/latex] cm. Class 7

Question 1.

A Celestial Pearl Danio’s length is 2[latex]\frac{4}{10}[/latex] cm, and the length of a Philippine Goby is [latex]\frac{9}{10}[/latex] cm. What is the diffrence in their lengths? Class 7

Solution:

Required diffrence = 2[latex]\frac{4}{10}[/latex]cm - [latex]\frac{9}{10}[/latex]cm

= [latex]\frac{24}{10}[/latex]cm - [latex]\frac{9}{10}[/latex]cm = [latex]\frac{24-9}{10}[/latex]cm

= [latex]\frac{15}{10}[/latex]cm = 1[latex]\frac{5}{10}[/latex]cm

Question 2.

Solution:

Do as directed and provide the answer.
