<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
A car consumes 6.8 liters of gasoline for every 102 kilometers traveled.
6.8 liters of gasoline = 102 km
1 liters of gasoline = 102 km/ 6.8
= 15
24 liters of gasoline = 24 x 15 = 360
Hence, The car can travel 360 km with 24 liters of gasoline.

Answer:
875%
Step-by-step explanation:
- 40cm÷100=.4m
- (3.5÷.4)*100%=
- (35÷4)*100%=
- 8.75*100%=
- 875%
- so 3.5m has 875%of 40cm
which means 875%*40cm is equal to 3.5
