I would recommend her to use kilograms:
grams are the standard weight unit used in the majority of the countries and in science- that's why it's better than pounds.
But kilograms are better than grams, since a watermelon weights around 2 kg, so it's easier to remember than 2000 grams.
Will it 150 if it's not I try
Rise over run! Y2-Y1/X2-X1
She could donate extra forks utensils and also donate spoon utensils and she will have the exact number of utensils as the knives
