75/100 + 3/4 x 29 + 75/100 x 30 + 0,75 x 40

= 0,75 x 1 + 0,75 x 29 + 0,75 x 30 + 0,75 x 40

Mình ko hiểu

Bạn viết lại đề bài đi rồi mình giải cho

75phan100 + 3phan4 x29 +76% x 30 + 0,75 x40

`75/100+3/4 *29+75% *30 + 0,75 * 40`

`= 0,75 + 0,75 * 29 + 0,75 * 30 +  0,75 * 40`

`= 0,75 * (1+29+30+40)`

`=0,75*100`

`=75`

\(\dfrac{75}{100}+\dfrac{3}{4}.29+75\%.30+0,75.40=\dfrac{75}{100}+\dfrac{75}{100}.29+\dfrac{75}{100}.30+\dfrac{75}{100}.40=\dfrac{75}{100}.\left(1+29+30+40\right)=\dfrac{75}{100}.100=75\)

= ( 75 : 100 ) + ( 3: 4 ) + ( 75 : 100 ) x 29 x 30 + 0,75 x 40

= 0,75 + 0,75 + 0,75 x 29 x30 + 0,75 x 40

= 0,75 x ( 29 + 30 + 40 )

= 0,75 x 100

= 75

tham khảo:

= ( 75 : 100 ) + ( 3: 4 ) + ( 75 : 100 ) x 29 x 30 + 0,75 x 40

= 0,75 + 0,75 + 0,75 x 29 x30 + 0,75 x 40

= 0,75 x ( 29 + 30 + 40 )

= 0,75 x 100

= 75
