In converting the temperature from Fahrenheit to Celsius the formula is, C = (5/9)(F – 32);
The steps of converting from Fahrenheit to Celsius are reversed here.
Step I
Subtract 32 from the degrees.
Step II
Multiply the result by 5
Step III
Divide the product by 9
1. Convert 86°F to the Celsius scale.
Solution:
Step I
Subtract 32 from the degrees.
= 86°  32
= 54°
Step II
Multiply the result by 5.
= 54° × 5
= 270°
Step III
Divide the product by 9.
= 270° ÷ 9
= 30° C
Therefore, 86° F = 30° C
2. Convert 104° F to the Celsius scale.
Solution:
Step I
Subtract 32 from the degrees.
= 104°  32
= 72°
Step II
Multiply the result by 5.
= 72° × 5
= 360°
Step III
Divide the product by 9.
= 360° ÷ 9
= 40° C
Therefore, 104° F = 40° C
3. Convert 113°F to the Celsius scale.
Solution:
Step I
Subtract 32 from the degrees.
= 113°  32
= 81°
Step II
Multiply the result by 5.
= 81° × 5
= 405°
Step III
Divide the product by 9.
= 405° ÷ 9
= 45° C
Therefore, 113° F = 45° C
4. Convert 122°F to the Celsius scale.
Solution:
Step I
Subtract 32 from the degrees.
= 122°  32
= 90°
Step II
Multiply the result by 5.
= 90° × 5
= 450°
Step III
Divide the product by 9.
= 450° ÷ 9
= 50° C
Therefore, 122° F = 50° C
