Question

(27/25-4/9)-(2/25-5/9)

Answer 1

\(\left(\dfrac{27}{25}-\dfrac{4}{9}\right)-\left(\dfrac{2}{25}-\dfrac{5}{9}\right)\)

\(=\dfrac{27}{25}-\dfrac{4}{9}-\dfrac{2}{25}+\dfrac{5}{9}\)

\(=\dfrac{27-2}{25}+\dfrac{5-4}{9}\)

\(=\dfrac{25}{25}+\dfrac{1}{9}\)

\(=1+\dfrac{1}{9}\)

\(=\dfrac{10}{9}\)

Answer 2

(27/25-4/9)-(2/25-5/9)

=27/25-4/9-2/25-5/9

=(27/25-2/25)-(4/9+5/9)

=          1        -1

= 0
