Final answer:
To solve 20⋅73y = 5, divide both sides by 20⋅ and round to the hundredths place if necessary, which in this example results in the solution y = 922.00.
Step-by-step explanation:
To find the solution to the equation 20⋅73y = 5, we must first isolate the variable y. By dividing both sides of the equation by 20⋅, we get:
y = 5 / (20⋅)
Using a calculator, we could find that the solution is a decimal. When we round this decimal to the nearest thousandth, we may get an answer like 921.996. However, if we want to provide the answer to the same degree of precision as the least precise number in the problem, we should round to the nearest hundredth. If the first digit to be dropped (in the thousandths place) is greater than 5, we round up to 922.00.
