Answer:
8
100
15
Step-by-step explanation:
8, because 1 has two 1/2s, and 4x1=4, 4x2=8. I multiplied 4 by 2 becuase two 1/2s fit in 1, and 4/1 is 4.
100, because 1/0.1=10, 10x10=100. I multiplied 10 by 10 because 10 0.1s fit in 1, and 10/1 is 10.
15, because 2/0.4 is 5, 5x3=15. I multiplied 5 by 3 because 5 0.4s fit in 2, and 6/2=3.
