3 1/3 = 10/3 = 30/9
she has 30/9 lbs of strawberries

Answer:
21
Step-by-step explanation:
divide 63 by 3
or
20x3=60
3x1=3
60+3=63
20+1=21 texts
1min: 100 ft
2min: 100(.5)= 50 ---> 100+50= 150 ft
3min: 50(.5)=25 ---> 150+25= 175 ft
4min: 25(.5)=12.5 ---> 175+12.5= 187.5 ft
5min: 12.5(.5)=6.25 ---> 187.5+6.25= 193.75ft
answer: 193.75 ft
Which expression represents the number of feet that are in x yards?
