Weight: How many grams does a 5 lb 15 oz roast weigh?The roast weighsgrams.

natulia [17]

Since 1kg = 2.20 lb,

$\frac{1\operatorname{kg}}{2.20\text{ lb}}$

Since 1kg = 1000g

$\frac{1000\text{ g}}{1\operatorname{kg}}$

So for covering pounds to gram by the following factor

$\frac{1\operatorname{kg}}{2.20\text{ lb}}\frac{1000\text{ g}}{1\operatorname{kg}}$

Since 1oz = 28.3g

$\frac{28.3\text{ g}}{1\text{ oz}}$

Now

$5\text{ lb}\frac{1000\text{ g}}{2.20\text{ lb}}+15\text{ oz}\frac{28.3g}{1\text{ oz}}$

The weight in grams would be

2697.22 gr

The body of a 154 pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum. Based on

KengaRu [80]

let a be aluminum and g be gold and k how many times:

2*10⁻¹mg a+ 6*10¹mg g= 154 lb

so a=kg

k=a/g

k=2*10⁻¹/6*10=1/300

a=1/300g

so Aluminum is 1/300 of gold.
