If 5 potatoes together have a mass of 1 kilogram and 8 pears together have a mass of 1,200 grams, which has the greater mass, A potato or A pear? Explain.
One kilogram is 1,000 grams. 1,200grams equals 1.2 kilograms because the 200 grams aren't yet a whole but you still have to remember that 200 grams is 1/5 of a kilogram; .2 x 5 = 1.
To put into shorter words, 1,200 grams is 1.2 kilograms so the pears are heavier than the potatoes.
