Question

What is equivalent Celsius value for $55{}^{\circ }\text{F}$?

• A. $12.78{}^{\circ }\text{C}$
• B. $11.78{}^{\circ }\text{C}$
• C. $21.78{}^{\circ }\text{C}$
• D. $23.78{}^{\circ }\text{C}$

Answer 1

The correct option is A $12.78{}^{\circ }\text{C}$

Given: F = $55{}^{\circ }\text{F}$, C = ?

We know that, F = $\frac{9}{5}$ C + 32

Solving for C, we get:

C = $\frac{5}{9}$(F - 32)

Therefore, for F = $55{}^{\circ }\text{F}$, we have:

C = $\frac{5}{9}$(55 - 32)

i.e. C = $12.78{}^{\circ }\text{C}$
