Question

A)(13,6-127,9)-(72,1-6,4)+181

B)-7/8+30%+4/13-0,125--9/13

Answer 1

A)=1

Answer 2

a =1

Answer 3

a) -114.3 - 65.7 +181 

= 1

b) \(\dfrac{-7}{8}+\dfrac{3}{10}+\dfrac{4}{13}-\dfrac{1}{8}-\dfrac{-9}{13}\)

\(=\left(\dfrac{-7}{8}-\dfrac{1}{8}\right)+\left(\dfrac{4}{13}-\dfrac{-9}{13}\right)+\dfrac{3}{10}\)

\(=-1+1+\dfrac{3}{10}\)

\(=\dfrac{3}{10}\)
