Answer
To determine the amount of flour for 12 people, first note that the recipe serves 6 people using 120 g of flour. We can find the flour required for 12 people by setting up a proportion:
Flour for 12 people=6 people120 g×12 people=240 g
Thus, Susumu should use 240 g of flour.

Answer
Abena has 1.3 kg of apples, which is equal to 1300 g. The recipe serves 6 people using 550 g of apples. To find the amount needed for 15 people, we can calculate:
Apple needed for 15 people=6 people550 g×15 people=1375 g
Since Abena has 1300 g of apples, and 1375 g is needed, she does not have enough apples to make apple crumble for 15 people. Hence, No, she cannot make apple crumble for 15 people.
