Answer 1

Question:

Solution

Let the expression:

`4(1)/(9)-(5)/(7)`

change to improper fractions:

`((4\cdot9)+1)/(9)-\text{ }(5)/(7)`

this is equivalent to:

`(37)/(9)-\text{ }(5)/(7)\text{ = }(259-45)/(63)=\text{ }(214)/(63)=\text{ 3.396}\approx3.40`

then the correct answers are:

`\text{ }(214)/(63)=\text{ 3.396}\approx3.40`
