48*9 209*4 765\9 384\8 109= дес ед 109см= дм см 2038= сот ед 2038 дм2= м2 дм2 6км м 9 см2= мм2

Answer 1

48*9=432
209*4=836
765/9=85
384/8=48

109см=10,9дм
20,38дм2=20,38м2
6км=6000м
9см2=90мм2

Answer 2

Let's calculate the values:

48 * 9 = 432 (multiplication) 209 * 4 = 836 (multiplication) 765 / 9 = 85 (division) 384 / 8 = 48 (division) 109 (no operation specified, so it remains the same)

109 decimeters (dm) = 1090 centimeters (cm) (conversion) 2038 square decimeters (dm^2) = 20.38 square meters (m^2) (conversion) 6 kilometers (km) = 6000 meters (m) (conversion) 9 square centimeters (cm^2) = 900 square millimeters (mm^2) (conversion)
