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

Answer 1

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.
