Step-by-step reasoning process: To make the cakes, Traci and Harris used a total of 9 cakes * 100g of flour per cake = 900g of flour. Traci therefore brought 900g of needed flour 400g of flour from Harris' flour = 500g of flour from her own house.
The question and answer:

The answer is 500

Step-by-step reasoning process: Josephine filled a total of 2 x 3 = 6 liters from the three containers with two liters each. She filled a total of 0.75 x 2 = 1.5 liters from the two containers with 0.75 liters each. She filled a total of 0.5 x 5 = 2.5 liters from the five containers with 0.5 liters each. Therefore, she sold a total of 6 + 1.5 + 2.5 = 10 liters of milk.
The question and answer:
Question and answer: On a Sunday morning, Josephine sold milk in the farm stall. The buyers brought their containers. She filled three containers with two liters each, two containers with 0.75 liters each, and five containers with 0.5 liters each. How many liters of milk did Josephine sell in total?
The answer is 10

Step-by-step reasoning process: Stella and Twinkle filled up the truck at the rate of 250 blocks per hour per person, a total of 2 * 250 = 500 blocks per hour for both. After working for four hours, Stella and Twinkle had filled 4 * 500 = 2000 blocks into the truck. The number of blocks they had to put into the truck for it to be full is 6000 - 2000 = 4000. When 6 more people joined Stella and Twinkle, a total of 2 + 6 = 8 people were filling the truck now. Working at the rate of 250 blocks per person, the eight people filled the truck with 250 * 8 = 2000 blocks in one hour. If there were 4000 blocks that still needed to be put into the truck, the 8 people took 4000 / 2000 = 2 hours to fill the truck with the blocks. The total time it took to fill up the tank is 4 + 2 = 6 hours.
The question and answer:
Question and answer:
Stella and Twinkle are filling up a truck with a capacity of 6000 stone blocks at the rate of 250 blocks per hour per person. They work for four hours and are then joined by 6 other people who also work at the same rate. How many hours did filling the truck take?
The answer is 6
