\(=0,75+0,75\times29+\frac{75}{100}\times30+0,75\times40\)

\(=0,75\times1+0,75\times29+0,75\times30+0,75\times40\)

\(\dfrac{75}{100}\) + 0,75 x 29 + 75% x 30 + \(\dfrac{3}{4}\) x 40

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

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

= 0,75 x 100

= 75

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

= 3/4 + 3/4 . 29 + 3/4 . 30 + 3/4 . 40

= 3/4 .(1 + 29 + 30 + 40)

= 3/4 . 100

= 75
