75/100+3/4×29+75/100×30+3/4×40= 3/4+3/4×29+3/4×30+3/4×40 = 3/4×1+3/4×29+3/4×30+3/4×40 = 3/4x(1+29+30+40) = 3/4 x 100 = 75 Trả lời
$\frac{75}{100}$ + $\frac{3}{4}$ x 29 + $\frac{75}{100}$ x 30 + $\frac{3}{4}$ x 40 = $\frac{3}{4}$ + $\frac{3}{4}$ x 29 + $\frac{75}{100}$ x 30 + $\frac{75}{100}$ x 40 = $\frac{3}{4}$ + $\frac{3}{4}$ x 29 + $\frac{3}{4}$ x 30 + $\frac{3}{4}$ x 40 = $\frac{3}{4}$ x (1 + 29 + 30 + 40) = $\frac{3}{4}$ x 100 = $\frac{300}{4}$ = 75 Trả lời
75/100+3/4×29+75/100×30+3/4×40
= 3/4+3/4×29+3/4×30+3/4×40
= 3/4×1+3/4×29+3/4×30+3/4×40
= 3/4x(1+29+30+40)
= 3/4 x 100
= 75
$\frac{75}{100}$ + $\frac{3}{4}$ x 29 + $\frac{75}{100}$ x 30 + $\frac{3}{4}$ x 40
= $\frac{3}{4}$ + $\frac{3}{4}$ x 29 + $\frac{75}{100}$ x 30 + $\frac{75}{100}$ x 40
= $\frac{3}{4}$ + $\frac{3}{4}$ x 29 + $\frac{3}{4}$ x 30 + $\frac{3}{4}$ x 40
= $\frac{3}{4}$ x (1 + 29 + 30 + 40)
= $\frac{3}{4}$ x 100
= $\frac{300}{4}$ = 75
