Question:

Solution

Let the expression:

[tex]4\frac{1}{9}-\frac{5}{7}[/tex]

change to improper fractions:

[tex]\frac{(4\cdot9)+1}{9}-\text{ }\frac{5}{7}[/tex]

this is equivalent to:

[tex]\frac{37}{9}-\text{ }\frac{5}{7}\text{ = }\frac{259-45}{63}=\text{ }\frac{214}{63}=\text{ 3.396}\approx3.40[/tex]

then the correct answers are:

[tex]\text{ }\frac{214}{63}=\text{ 3.396}\approx3.40[/tex]
