Write and solve a proportion to complete the statement. Round your answer to the nearest hundredth. 90 lb ≈ kg

1 kg = 2.2 lb

to set up your proportion

- put your given over one

90lb / 1

then multiply that by you conversion factor which is 1 kg = 2.2 lb

90lb/1 x 1kg/2.2lb

since you have lb on both the top and bottom that unit would cancel out leaving you with kg

if you multiply straight across you get 90 x 1 = 90 and 1 x 2.2 = 2.2

now you just divide the top number by the bottom number 90 : 2.2 = 40.91 kg

40.82 kg beacause one kg is 2.20462 pounds so if you add all that together it all adds up to that.
