Question

1. Convert from °C to °F.
(a) 15°C
(b) 28​

Answer 1

[°F = 9/5 (C) + 32] ——––--> Formula

(a) 15°C = ___ °F

°F = 9/5 (C) + 32

= 9/5 (15) + 32

= 135/5 + 32

= 27 + 32

= 59°F (Answer)

(b) 28°C = ___ °F

°F = 9/5 (C) + 32

= 9/5 (28) + 32

= 252/5 + 32

= LCM of 5 & 1 = 5

= 252/5 + 160/5

= 412/5 °F

= 82.4°F (Answer)
