Question

( 3/4 + 0,5 + 25% ) . hai và hai phần ba 

Answer 1

= \(\left(\dfrac{3}{4}+\dfrac{1}{2}+\dfrac{1}{4}\right).2\dfrac{2}{3}=\left(1+\dfrac{1}{2}\right).\dfrac{8}{3}=\dfrac{3}{2}.\dfrac{8}{3}=\dfrac{8}{2}=4\)

Answer 2

=> [ 3/4 + 1/2 + 1/4 ] x 8/3

=> [ (3/4 + 1/4 ) + 1/2] x 8/3

=> [1 + 1/2 ] x 8/3

=> 3/2 x 8/3 

=> 8/2 = 4/1 = 4

Answer 3

`(3/4+0,5+25%) xx 2 2/3`

`=(3/4+1/2+1/4)xx8/3`

`=( (3/4+1/4)+1/2)xx8/3`

`=(1+1/2)xx8/3`

`=3/2xx8/3`

`=8/2=4`

Answer 4

`= (3/4 + 1/2 + 1/4) xx 2 2/3`

`= 3/2 xx 8/3`

`= 4.`
