Question

How you do the Ladder method?/

109g =kg?

160cm=mm?

Answer 1

I'm not sure whether this is the Ladder Method, going from one power-of-10 unit to the next and moving the decimal point one place accordingly, until getting to the desired unit, but:

kilograms = 1,000 grams

Smaller unit to bigger unit; the number decreases. Move the decimal point to the left one place (divide by 10) to get to each unit.

109g ---> 10.9 * 10g ---> 1.09 * 100g ---> 0.109 kg

answer: 0.109 kg

160 cm = ? mm

Centimeters (100 m) to millimeters (1000 m), a bigger unit to a smaller unit, so the number increases.

One step in this case; move the decimal point right one place (add a zero on the right side).

160 cm ---> 1,600 mm

answer: 1,600 mm

Answer 2

1000kg= 1g

therefore, using diminesonal analysis

(109g)*(1000kg)/1g

The units of grams cancel your answer than is 1.09*10^-3 kg

No clue to what ladder method is

Answer 3

109g= kg

kilo(thousand) gram.

109= 109.0

move the decimal to the thousandth place.

that's three places to the left.

You'll get 0.109.

So 109 grams equal 0.109 kilograms.
