a) \(635.25-25.235\)
\(=25.\left(635-235\right)\)
\(=25.400\)
\(=10000\)
b) \(425.73+100-27\)
\(=31025+73\)
\(=31098\)
c) \(8.63.125\)
\(=\left(8.125\right).63\)
\(=1000.63\)
\(=63000\)
A) 635.25 - 25.235
= 25.(635 - 235 )
= 25.400
= 10000
B) 425.73 + 100 - 27
= 31025 + 73
= 31098
C) 8.63.125
= (8.125).63
= 1000.63
= 63000
