If a person has 2.5 kilograms of hmaburger meat,how many pounds do they have?

Question

There are 2.2 pounds in a kilogram. If a person has 2.5 kilograms of hamburger meat how many pounds do they have?

Answer 1

This is a unit conversion problem. Convert kg -> lbs.

If you had 1 kg, how many lbs is that? Easy, you know it'd be 2.2 lbs.

So now do some more examples. What if you had 2 kg of meat? It'd be like having twice of the previous example, so 2 kg * 2.2 lbs / kg is 4.4 lbs.

What about 3 kg? You'd have 3 times that first example, which would be 3 kg * 2.2 lbs / kg = 6.6 lbs.

Now, the real question is 2.5 kg of meat. So 2.5 kg * 2.2 lbs / kg = 5.5 lbs.

Answer 2

Since you already know that there are 2.2 pounds in a kilogram, you can multiply 2.2 by the amount of kilograms you have of hamburger meat. So, 2.2 x 2.5 -- this will convert the kilograms to pounds. When you multiply decimals, be sure to move the decimal point as many places over as are in the problem (in this case, 2 places).

 

Another way to figure this out is to draw 2 and 1/2 "lumps of meat". Inside each of the whole lumps, write 2.2, for the amount of pounds in that kilogram of meat. Inside the 1/2 lump, write 1.1 (half of 2.2), for the amount of pounds in that lump. Add 2.2+2.2+1.1.

Answer 3

Try multiplying the number of kilograms by the number of pounds in a kilogram.

 

(2.5 kg)(2.2 lbs/kg) = ? lbs
