Answer:
0.4
Step-by-step explanation:
4 juniors out of a total of 10
4/10 = 0.4
Step-by-step explanation:
2/3 gallons is empty
1/3 gallons is filled
so
3*1/3= 1
1 gallon filled
9/10 - 5/10
because the denominators are the same you keep it and just subtract the numerators
=4/10
This can be reduced to 2/5
-11/12 +5/12 = - 6/12= - 1/2
