Answer:

116°F = 46.67 °C and 6 Pounds = 2721.55 grams

Step-by-step explanation:

The information given in the question is 1°F = -17.22°C

1 Kilogram = 1000 grams = 2.2 pounds

And we have to convert 116° F to degrees Celsius and Six pounds to grams.

1) We know (°F-32)×5/9 =°C

So by putting the value of °F as 116 ⇒ (116-32)×5÷9 = °C

⇒ °C = $\frac{(84)(5)}{9}$

⇒ °C = 46.67

2). ∵ 2.2 Pounds = 1000 grams

∴1 Pound = 1000/2.2 = 454.54 grams

∴ 6 pounds = 6× 454.54 grams

= 2721.55 grams
