Step 1: Find out how many kilograms of onions Hiro will use. 
(1 gram= 0.001 kilogram)
550 grams= 0.55 kilograms

Step 2: Find out how much produce was not used for potatoes and onions
5 kg- 3.25 kg = 1.75 kg
2 kg-0.55 kg= 1.45 kg

Step 3: Add together the unused produce.

1.75 + 1.45= 3.2 kg were not used.
