Question

Tính

11/2-(7/5-1/2)

Answer 1

\(\dfrac{11}{2}-\left(\dfrac{7}{5}-\dfrac{1}{2}\right)=\dfrac{11}{2}-\left(\dfrac{14}{10}-\dfrac{5}{10}\right)=\dfrac{11}{2}-\dfrac{9}{10}=\dfrac{55}{10}-\dfrac{9}{10}=\dfrac{46}{10}=\dfrac{23}{5}\)

Answer 2

=11/2-9/10

=23/5

Answer 3

`11/2-(7/5-1/2)=11/2-9/10=46/10`

Answer 4

\(\dfrac{23}{5}\)

Answer 5

\(\dfrac{11}{2}-\left(\dfrac{7}{5}-\dfrac{1}{2}\right)=\dfrac{11}{2}-\left(\dfrac{14}{10}-\dfrac{5}{10}\right)=\dfrac{11}{2}-\dfrac{9}{10}=\dfrac{55}{10}-\dfrac{9}{10}=\dfrac{46}{10}=\dfrac{23}{5}\)

Answer 6

11/2−(7/5−1/2)=11/2−(14/10−5/10)=11/2−9/10=55/10−9/10=46/10=23/5
