A=71 38/45-(43 8/45 + 1 17/57)

Answer 1

A=71 38/45-(43 8/45 + 1 17/57)

=( 71 38/45-43 8/45 )+ 1 17/57

= 28 2/3 + 1 17/57

= 29 55/57

Answer 2

\(A=71\frac{38}{45}-\left(43\frac{8}{45}+1\frac{17}{57}\right)\)

\(A=\frac{3233}{45}-\left(\frac{1943}{45}+\frac{74}{57}\right)\)

\(A=\frac{3233}{45}-\frac{1943}{45}-\frac{74}{57}\)

\(A=\frac{86}{3}-\frac{74}{57}=\frac{520}{19}\)
