a) \(63,45\times3,2-2\times63,45-63,45\times0,2\)
\(=63,45\times\left(3,2-2-0,2\right)\)
\(=63,45\times1\)
\(=63,45\)
b) \(5,67\times4,8+5,67\times4,2+5,67\)
\(=5,67\times\left(4,8+4,2+1\right)\)
\(=5,67\times10\)
\(=56,7\)

a) 12,3 + 5,67 = 17,97
12,3 - 5,67 = 6,63
b) ( -12,3) + (-5,67) = -(12,3 + 5,67) = -17,97
5,67 - 12,3 = -(12,3 - 5,67)= - 6,63

\(25\cdot\left(x-3,4\right)-5,67=7,23\)
\(25\cdot\left(x-3,4\right)=7,23+5,67\)
\(25\cdot\left(x-3,4\right)=12,9\)
\(x-3,4=12,9\text{ : }25\)
\(x-3,4=0,516\)
\(x=0,516+3,4\)
\(x=3,916\)

x + 5,67 = 18,3 - 6,98
x + 5,67 = 11,32
x = 11,32 - 5,67
x = 5,65
Vậy x = 5,65

\(a)\) \(5,67 \) \(\times \) \(2,5 \) \(\times\) \(0,4\)
\(= 5,67 \) \(\times \) \(( \) \(2,5 \) \(\times \) \(0,4 \) \() \)
\(= 5,67 \times 1 \)
\(= 5,67\)
\(b) \) \(1,47 \times 3,6 + 1,47 \times 6,4\)
\(= 1,47 \times ( 3,6 + 6,4 )\)
\(= 1,47 \times 10 \)
\(= 14,7\)
\(c) \) \(0,25 \times 0,68 \times 40 + 25,8 \times 1,02 - 25,8 \times 1,01\)
\(= 0,68 \times ( 0,25 \times 40 ) + 25,8 \times 1,02 - 25,8 \times 1,01\)
\(= 0,68 \times 1 + 25,8 \times ( 1,02 - 1,01 )\)
\(= 0,68 + 25,8 \times 0,01\)
\(= 0,68 + 0,258 \)
\(= 0,938\)
