Answer:
42.8°C
Step-by-step explanation:
To convert from degrees centigrade to degrees fahrenheit, we use this formula;
(C × ) + 32
Where C is the temperature in degrees centigrade.
So,
(C × ) + 32 = 109°F
C = 109 - 32
C = 77
C = 77 × = 42.77777778°C
It equals 42.8°C (rounded up to nearest tenth of a degree centigrade)
it would be 100.01% That is because in a percentage you have to move the decimal point two places to the right.
