\(\frac{4}{5}x\frac{1}{20\%}+0,08=4,08\)
\(2001:25-1999:25=0,08\)
\(75x1,25=93,75\)

4/5 x 1/20% + 0,08 = 4 + 0,08
= 4,08
2001 : 25 - 1999 : 25 = 80,04 - 79,96
= 0,08
75 x 1,25 = 93,75
56 x 2,5 x 400 = 56 x 1000
= 56 000
1600 : 1,25 = 1280
xong rồi đó
\(\frac{4}{5}X\frac{1}{20\%}+0,08=\frac{4}{5}X\frac{1}{\frac{1}{5}}+0,08=\frac{4}{5}X5+0,08=4+0,08=4,08\)
\(2001:25-1999:25=\left(2001-1999\right):25=2:25=0,08\)
\(75X1,25=75X\frac{5}{4}=93,75\)
\(56X2,5X400=56X\left(2,5X400\right)=56X1000=56000\)
\(1600:1,25=1600:\frac{5}{4}=1280\)
