Answer 1

Answer: 22

Explanation:

(1 × 3) + [2 × 3
`(1)/(2)`] + [1 × 3
`(3)/(4)` [1 × 4
`(1)/(4)`] + [3 ×
`(3)/(4)`] + [3 × 5
`(1)/(4)`]

= 3 + [2 ×
`(3)/(2)`] + [1 ×
`(9)/(4)`] + [1 ×
`(4)/(4)`] + [3 ×
`(12)/(4)`] + [3 ×
`(5)/(4)`]

= 3 +
`(6)/(2)` +
`(9)/(4)` +
`(4)/(4)` (equal to 1) +
`(36)/(4)` +
`(15)/(4)`

= 3 + 3 +
`(9)/(4)` + 1 + 9 +
`(15)/(4)`

= 16 +
`(9+15)/(4)`

= 16 +
`(24)/(4)`

= 16 + 6

= 22
