Question

450% + 3 1/4 - 2,75 + 2 3/10 + 2,7

Answer 1

`450%+3 1/4 -2,75+ 2 3/10 +2,7`

`->4,5+3,25−2,75+2,3+2,7`

`->[(4,5+3,25)−2,75]+(2,3+2,7)`

`->[7,75-2,75]+5`

`->5+5->10`

Answer 2

\(=\dfrac{9}{2}+\dfrac{13}{4}-\dfrac{11}{4}+\dfrac{23}{10}+\dfrac{27}{10}\\ =\dfrac{9}{2}+\dfrac{1}{2}+5\\ =5+5=10\)
