Answer:
Interphase: 55.56%
Prophase: 27.78%
Metaphase: 8.33%
Anaphase: 5.56%
Telophase: 2.78%
Explanation:
All you need to do is follow the instructions. To get the percentage, all you need to do is divide the part by the whole then multiply it by 100%.
![(Part)/(Whole)* 100\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ohn10hhplgvt0292lr3lapkm9abg1etx9m.png)
Now let's take your problem:
Number of cells in interphase:
20 this is the part and the whole would be the total cells, which is 36. Now we insert that into our equation:
![(20)/(36)* 100\%=0.5556*100\%=55.56\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9jppcglso5gfuowpnox32oimbon2wl5107.png)
So now we apply the same to the rest:
Prophase:
![(10)/(36)* 100\%=0.2778*100\%=27.78\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zily1qdcmkvsni0nij1g0ud1ingfeydil7.png)
Metaphase:
![(3)/(36)* 100\%=0.0833*100\%=8.33\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tvnbjbenmxcd01rmiuhndxaj12g11fy1zv.png)
Anaphase:
![(2)/(36)* 100\%=0.0556*100\%=5.56\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4exnzfd7otkdfyxqumem5g1hv76wmddksp.png)
Telophase:
![(1)/(36)* 100\%=0.0278*100\%=2.78\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fk3a94onso072zw3mwsur0jnj74srgtr22.png)
