Question

Now you'll complete the temperature part of the problem again but this time using decimal numbers. Start by converting the temperatures in the problem statements from fractions to decimals.

a) Multiply each temperature by 0.5
b) Divide each temperature by 10
c) Subtract 0.5 from each temperature
d) Convert each temperature to its decimal equivalent

Answer 1

The task involves converting temperatures between Fahrenheit and Celsius and performing arithmetic operations on decimal numbers, including converting fractions to decimals, multiplication, division, and subtraction.

Step-by-step explanation:

The question involves the process of converting temperatures between different units and performing arithmetic operations with decimal numbers. To accomplish these tasks, we'll need to:

• Convert fractions to decimals.
• Multiply these decimal temperatures by 0.5.
• Divide the temperatures by 10.
• Subtract 0.5 from each temperature.
• Use the conversion formulas to switch between Fahrenheit and Celsius temperatures.

For example, converting a decrease of 40.0°F to Celsius involves knowing that the temperature change in Celsius is nine-fifths that of Fahrenheit. Therefore, we multiply the decrease by 5/9 to find the change in Celsius:

°C decrease = (°F decrease) × (5/9)

In this case:

°C decrease = (40.0°F) × (5/9) = 22.2°C

Be sure to check that the answer is reasonable and makes sense in the context of the problem.
