\(a.467\times65+35\times467\) \(b.678\times74+27\times678-678\)
\(=467\times\left(65+35\right)\) \(=678\times74+27\times678-678\times1\)
\(=467\times100\) \(=678\times\left(74+27-1\right)\)
\(=46700\) \(=678\times100\)
\(=67800\)

75% × 68 + 75/100 × 31 + 0,75
= 75/100 × 68 + 75/100 × 31 + 75/100 × 1
= 75/100 × (68 + 31 + 1)
= 75/100 × 100
= 75
