Rose had 10 kilograms of rice. She cooked 9/10 kilograms in the morning and 1/4 of the remaining in the evening. How many grams of rice did she have left?
Rose cooked 10 x 9/10 = <<10*9/10=9>>9 kilograms of rice in the morning.
She had 10 - 9 = <<10-9=1>>1 kilogram of rice left then.
One kilogram is equal to 1 x 1000 = <<1*1000=1000>>1000 grams.
So, Rose cooked 1000 x 1/4 = <<1000*1/4=250>>250 grams of rice in the evening.
Therefore, she has 1000 - 250 = <<1000-250=750>>750 grams of rice left.
