One equation that represents this situation is f/4 = 22.
This shows the total number of flowers (f) being broken into 4 groups (4 vases) with the result being 22 flowers in each vase.
You need to find what 34 is 25% of.
I personally would take 34 and divide it by .25 (25%) to get your answer and then to double check it, multiple the answer you get by 25%
so originally the farmer had 136 kg of apples of I'm not mistaken.
