Answer 2

It is easy, Jalil
Look
we firstly simplify the first fraction
\[1\frac{ 7 }{ 9 } = \frac{ 16 }{ 9 }\]
This is accomplished by the following: 1*9=9 9+7=16 then 16/9

Answer 3

as the two denominators of both fractions are the same, we will unify the denominators, so let's subtract directly
\[\frac{ 16 }{ 9 } - \frac{ 4 }{ 9 } = \frac{ 16-4}{9 }=\frac{ 12 }{ ? }\]

Answer 4

?=9

Answer 5

Then simplify the fraction, it will be at the form:
\[\frac{ 12 }{ 9 }=\frac{ 12/3 }{ 9/3 }=\frac{ 4 }{ 3 }\]

Answer 6

Hope you got that and understand it as well.
