A total of more than 600 kilograms of rice and flour were bought in the canteen of the fourth grade mathematics school in primary school. Buy four times as much flour as rice. How many thousands of rice and flour did you buy respectively? Flour is 4 times and * * 5 times that of rice (4 times that of flour and 1 times that of rice), so:

600/(4+ 1)= 120

120 is the weight of rice, 600- 120 = 480 (kg).

I bought 120kg of rice and 480kg of flour.
