Answer:
17/49 or about 34.7%
Step-by-step explanation:
George has 85 cards out of 245 cards that are pitchers. Whever you hear "out of", it means to divide.
85/245 are pitchers.
you can simplify since 5 fits in both of those numbers
5*17=85
5*49=245
So, 17/49 or about 34.7%
Answer:
1) 28.4 miles per gallon
2) 34 miles per gallon
3) the red car
Step-by-step explanation:
Blue car:
Travels 35 1/2 miles on 1 1/4 gallons of gasoline
Red car:
Travels 27 1/5 miles on 4/5 gallons of gasoline
We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:
Blue car:
(35 1/2) / (1 1/4) = 28.4 miles per gallon
Red car:
(27 1/5) / (4/5) = 34 miles per gallon
The red car travels greater distance with 1 gallon of gasoline {and thats about it!}
