Answer 1

Question:

Solution

Let the expression:

$4\frac{1}{9}-\frac{5}{7}$

change to improper fractions:

$\frac{(4\cdot9)+1}{9}-\text{ }\frac{5}{7}$

this is equivalent to:

$\frac{37}{9}-\text{ }\frac{5}{7}\text{ = }\frac{259-45}{63}=\text{ }\frac{214}{63}=\text{ 3.396}\approx3.40$

then the correct answers are:

$\text{ }\frac{214}{63}=\text{ 3.396}\approx3.40$
