they say bongani buys 1 liter of milk and drinks a quarter of it and they want to know what fraction of the liter of milk is left,and they say bongani offers another 3eighths of the leftover milk to his sister bongiwe and they want to know what fraction of the litter of milk is left

Ok,I fixed most of it I think.

To find out what fraction of the liter of milk is left, we need to perform some calculations based on the given information.

First, let's determine how much milk is left after Bongani drinks a quarter of it. If Bongani initially bought 1 liter of milk, he drinks 1/4 of it, which is equal to (1/4) x 1 = 1/4 liter.

To find out what fraction of the milk is left, we subtract the amount Bongani drank from the initial amount he bought: 1 - 1/4 = 3/4 liter.

Now, Bongani offers another 3/8 of the remaining milk to his sister, Bongiwe. To calculate this, we need to find 3/8 of 3/4.

To multiply fractions, we multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator. So, (3/8) x (3/4) = (3 x 3) / (8 x 4) = 9/32 liter.

Therefore, the fraction of the liter of milk left after Bongani offers his sister some is 9/32.
