Simphiwe watered half of his vegetable garden on monday and 3/5 of the garden on tuesday if the garden is 24m square in size determine how big is the portion he still needs to water
On Monday, Simphiwe watered half of his garden, which is equivalent to 1/2 * 24m^2 = 12m^2.
On Tuesday, he watered 3/5 of the garden, which is equivalent to 3/5 * 24m^2 = 14.4m^2.
So far, he has watered a total of 12m^2 + 14.4m^2 = 26.4m^2 of the garden.
The portion he still needs to water is equal to the total size of the garden minus the portion he has already watered:
24m^2 - 26.4m^2 = -2.4m^2
Therefore, the portion he still needs to water is 2.4m^2.
