Question

I need help with both

Answer 1

28. Switch everything to eights:

`( (1)/(8)) +4( (4)/(8) )+( (5)/(8) )+2( (6)/(8) )+( (7)/(8)) )= (41)/(8)` this represents the sum of the pieces shown on the graph.

Now we add the 1 foot left over:
`(41)/(8) + (8)/(8) = (49)/(8) =6 (1)/(8)`

29.Answer is choiice D..
`(3)/(3) =1` and 1 x 12 = 12 so any number for 'k' greater than 3 will create a factor greater than '1' to be multiplied by 12 resulting in a product greater than 12.
