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?
Please answer the following question by reasoning step-by-step.
750
Rose cooked 10 x 9 / 10 = 9 kilograms of rice in the morning.

She had 10 - 9 = 1 kilogram of rice left then.

One kilogram is equal to 1 x 1000 = 1000 grams.

So, Rose cooked 1000 x 1 / 4 = 250 grams of rice in the evening.

Therefore, she has 1000 - 250 = 750 grams of rice left.

The answer: 750
