Question

\(\frac{19}{10}-\left(\frac{2}{35}-\frac{1}{10}\right)-\frac{33}{35}\)

Answer 1

19/10 - (2/35 - 1/10 ) - 33/35

= 19/10 - 2/35 + 1/10 - 33/35

= (19/10 + 1/10) - (2/35 +33/35)

= 2 - 1

= 1

Answer 2

\(\frac{19}{10}-\left(\frac{2}{35}-\frac{1}{10}\right)-\frac{33}{35}\)

\(=\frac{19}{10}-\frac{2}{35}+\frac{1}{10}-\frac{33}{35}\)

\(=\left(\frac{19}{10}+\frac{1}{10}\right)-\left(\frac{2}{35}-\frac{33}{35}\right)\)

\(=2-\left(-1\right)=3\)
