X × 99 + x = 432 + 568
X × 99 + x × 1 = 1000
X × (99 + 1 )=1000
X × 100 = 10
X =10

45 x X + 28 = 568
45 x X= 568-28
45 x X= 540
x= 540:45
x= 12

\(\frac{315}{316}\cdot\frac{316}{314}\cdot\frac{316}{315}\cdot\frac{317}{313}=\frac{315.316.316.317}{316.314.315.313}=\frac{1.1.316.317}{1.314.1.313}=\frac{100172}{98282}\)
Ta có : \(\frac{3}{2}\times\frac{4}{5}\times\frac{2}{3}\)
\(=\frac{3}{2}\times\frac{2}{3}\times\frac{4}{5}=1\times\frac{4}{5}\)
\(=\frac{4}{5}\)

8.725 x 3.267 + 3.267 x 1.725 - 12.627
= 3.267 x ( 8.725 + 1.725 ) - 12.627
= 3.267 x 10.45 - 12.627
= 34.14015 - 12.627
= 21.51315
8,725 x 3,267 + 3,267 x 1,725 - 12,627 = (8,725 + 1,725) x 3,267 - 12,627
= 10,45 x 3,267 - 12,627
= 34,14015 - 12,627
