4/5 as a percent would be 80% because 100 divided by 5 is 20 then multiply by 4 which is 80%. Then for the 1 which is a whole equals 5/5 so it would be 100% which you add to the percent of the 4/5 and it would be 180% total.
The difference between vertical angles and linear pairs of angles is that linear pairs of angles has two adjacent angles whose noncommon sides form opposite sides and vertical angles have two adjacent angles that have common sides that and they have a common vertex.
These are the possible dimensions:
1) 12 x 1 x 1
2) 6 x 2 x 1
3) 3 x 4 x 1
4) 3 x 2 x 2
