answer: first box 8 and 10
second box 4 and 6
step-by-step explanation:
for the first one
2/5=0.4
0.4x20=8
0.4x25=10
for the second one
2/11=0.1818181818181818
0.1818181818181818x22=4
0.1818181818181818x33=6
the reason why we divided the 2 by the 5 is because if we multiply the 0.4 by the 5 it will give us 2. but if we multiply 0.4 by the 2 it will not give us 5.
