No they are not all rational numbers
'dz' because d and z are different values.
0.65625 is the decimal product of the fractions 3/4 & 7/8 whereas 7/8 can be simplified to 0.875 in decimal form... comparing both the values, we see that 7/8 is greater than the product of 3/4 and 7/8.
Answer:
Ann drove 312 miles in 8 gallons.
Step-by-step explanation:
Distance covered by Ann's car = 117 miles
Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons
Unit rate = 117 miles / 3 gallons
= 39 miles per gallon
so Ann's car can go 39 miles in one gallon of gas.
- Given that Ann used 8 gallons of gas.
Therefore,
Distance covered by Ann's car in 8 gallons = 39 × 8
= 312 miles
Therefore, Ann drove 312 miles in 8 gallons.
