1. 384 dam + a = 512 dam
a = 512 dam - 384 dam
a = 128 dam
V : 384 dam + 128 dam = 512 dam
---------------------------------------------------------
2. b x 10 = 720 cm
b = 720 cm : 10
b = 72 cm
V : 72 x 10 = 720 cm
--------------------------------------
3. c - 83 dm = 248 dm
c = 248 dm + 83 dm
c = 331 dm
V : 331 dm - 83 dm = 248 dm
------------------------------------------------
4. d : 6 = 48 cm
d = 48 cm x 6
d = 288 cm
V : 288 cm : 6 = 48 cm
--------------------------------------------------
5. 700 mm : e = 100 mm
e = 700 mm : 100 mm
e = 7 mm
V : 700 mm : 7 mm = 100 mm
-----------------------------------------------------
6. 1000 dam - f = 278 dam
f = 1000 dam - 278 dam
f = 722 dam
V : 1000 dam - 722 dam = 278 dam
