Question

Help me please Idk how to do it

Answer 1

1. 80/100
2. 12 1/2 over 100
3. 10/100

Explanation:

1. The colored ones all equal 80 because all the square represents 1 unit
2. The same thing with the second one but there one that's half colored so it would represent 1/2
3. The same thing goes for the last one but they just colored the bottom row but it equals 10 because it going by 100 all the rows have 10 in them

Sorry but I don't remember how to do the percentage one
