The shaded portions of the squares in the picture attached represents 25%, 50%, and 150% respectively.
A whole square represents 100% ;
For 25%
We Divide the square into 4 equal sizes,
100% / 4 = 25% for each portion of the division.
For 50%:
We divide the square into 2 equal portion ;
100% / 2 = 50% for each portion of the divison.
To obtain 150%,
(100% + 50%) ; this can be modeled thus ;
1 whole square + (1 whole square divided by 2)
The different figures are represented in the picture attached below.
