7) Write the decimal number as a fraction
(over 1)
2.18 = 2.18 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator (N)
N = 2.18 × 10 × 10 × 10 = 2180
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000
N / D = 2180 / 1000
Simplifying our fraction
= 2180/1000
= 109/50
= 2 9/50

Answer:
Average speed is 3 kilometers an hour
Answer:
a + c = 125 & 12a + 6c = 1140
Step-by-step explanation:
adult ticket total + child ticket total = 125 total tickets
($12 x adult ticket total) + ($6 x child ticket total) = $1140
