Question

Convert 357°C into °F
​

Answer 1

F= 9/5×°c +32

F= 9/5×357 +32

F=3213/5+32

F=3213+160/5 (l.c.m)

F=3373/5

F=674.6

Answer 2

$<b>$

$\huge\frac{tf - 32}{180} = \frac{tc - 0}{100} \\ \\ \huge\frac{tf - 32}{18} = \frac{357- 0}{10} \\ \\ \huge10f - 320 = 18 \times 357 \\ \\ \huge \mathfrak{ 10f = 6426 + 320} \\ \\ \red{ \huge \boxed{ \mathfrak{ f = 674.6}}}$
