Question
John had some flour and wanted to cook meals for his parents. He used 23 kg for lunch and 49 kg for dinner. After that, he had 49 kg of flour left. How much flour did he have at first? Express your answer in mixed number and simplest form
Solution
To solve this problem, we need to add the amount of flour John used for lunch and dinner to the amount he had left.
Step 1: Add the amount of flour used for lunch and dinner. 23 kg (for lunch) + 49 kg (for dinner) = 72 kg
Step 2: Add the result to the amount of flour left. 72 kg + 49 kg (left) = 121 kg
So, John had 121 kg of flour at first.
In mixed number form, 121 is already a whole number, so it doesn't need to be converted. In simplest form, it is also 121 because it cannot be simplified any further.
