Hiro has 5 kilograms of potatoes and 2 kilograms of onions. He plans to use 3.25 kilograms of potatoes and 550 grams of onions f

spayn [35]

Answer: 3.20kg

Step-by-step explanation:

Hiro has 5 kilograms of potatoes and 2 kilograms of onions. The total kilogram of the produce will be:

= 5kg + 2kg

= 7kg

Since he plans to use 3.25 kilograms of potatoes and 550 grams of onions for a recipe. The total kilogram that he plans to use will be:

= 3.25kg + 0.55kg

= 3.80kg

Therefore, the total kilograms of the produce will not be used will be:

= 7kg - 3.80kg

= 3.20kg

Note:

1000grams = 1 kilogram

550gram = 550/1000 = 0.55kg
