\(\frac{75}{100}+\frac{3}{4}\times29+75\%\times30+0,75\times40\)
\(=0,75+0,75\times29+\frac{75}{100}\times30+0,75\times40\)
\(=0,75\times1+0,75\times29+0,75\times30+0,75\times40\)
\(=0,75\times\left(1+29+30+40\right)\)
\(=0,75\times100\)
\(=75\)

\(=\dfrac{3}{4}\left(28+23+1+48\right)=\dfrac{3}{4}\cdot100=75\)
\(=\dfrac{3}{4}\left(1+29+30+40\right)=\dfrac{3}{4}\cdot100=75\)
\(\frac{75}{100}+\frac{3}{4}\times29+75\%\times30+0,75\times40\)
\(=0,75+0,75\times29+0,75\times30+0,75\times40\)
\(=0,75\times(1+29+30+40)\)
\(=0,75\times100\)
\(=75\)
(75 / 100) + ((3 / 4) x 29) + (75% x 30) + (0,75 x 40) =
75 |
75% × 68 + 75/100 × 31 + 0,75
= 75/100 × 68 + 75/100 × 31 + 75/100 × 1
= 75/100 × (68 + 31 + 1)
= 75/100 × 100
= 75
75%x68+75/100x31+0,75
=0,75x68+0,75x31+0,75
=0,75x(68+31+1)
=0,75x100=75
