Answer:
multiplication property of Equality
Answer:
55 hours
Step-by-step explanation:
Write the problem as an equation.
4290-78x=0
Where 'x' is each hour the pond is being drained.
Then, solve.
4290=78x Add 78x to each side of the equation
55=x Divide both sides by 78
Write the decimal number as a fraction (over 1)
23.8 = 23.8 / 1
Multiplying by 1 to eliminate 1 decimal places
we multiply top and bottom by 1 10's
Numerator (N)
N = 23.8 × 10 = 238
Denominator (D)
D = 1 × 10 = 10
N / D = 238 / 10
Simplifying the fraction
238/10 = 119/5= 23 4/5
FINAL ANSWER: 23 4/5
