`(1/22 +1/13 - 0,5)/(3/13 - 3/2 + 3/22) × (3/4 - 0,375 + 3/16 - 3/32)/(1 - 1/2 + 1/4 - 0,125) + 3/4`
`= (1/22 + 1/13 - 1/2)/(3/22 + 3/13 - 3/2) × (3/4 - 3/8 + 3/16 - 3/32)/( 4/4 - 4/8 + 4/16 - 4/32) + 3/4`
`= (1/22 + 1/13 - 1/2)/(3 (1/22 + 1/13 - 1/2) ) × (3 (1/4 - 1/8 + 1/16 - 1/32) )/(4 (1/4 - 1/8 + 1/16 - 1/32) ) + 3/4`
`= 1/3 × 3/4 +3/4`
`= 1/4 + 3/4`
`= 1`
