18/20 + 8/20 - 5/20 = 21/20 or 1 and 1/20
The sum of 1/2 and 2/5 is 9/10
Overland - Plus or Minus 10 miles; Plus or minus 5 minutes Oversea - Plus or Minus 20 miles; Plus or minus 5 minutes
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
20 + 10 - 31 + 30 - 5 = 24
18 + 12 + 0 - 4 - 10 = 16
The sum of 1/2 and 2/5 is 9/10
Overland - Plus or Minus 10 miles; Plus or minus 5 minutes Oversea - Plus or Minus 20 miles; Plus or minus 5 minutes
1 over 10 as a percentage = 10%=1/10 * 100%= 10%
1over 10 because you cant divide one
10%
(-45) - (-55) *Minus plus is equals to minus.( -,+ = - ) minus minus is equal to plus (-,- = + ) and plus plus is equal to plus (+,+ = +) so the ans is that, (-45) +55 -45 + 55 (+10)ans Greater value sign has been used, which is 55 so the ans is +10.
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
NO!!!! Here is a table for multiplication/division of 'double (+/-) signs.'. (+)(+) = (+) (+)(-) = (-) (-)(+) = (-) (-)(-) = (+) Sometimes in higher level maths, you can have triple signs. Here is the table. (+)(+)(+) = (+)(+) = (+) (+)(-)(-) = (-)(+) = (-) (-)(+)(+) = (-)(+) = (-) (-)(-)(-) = (+)(-) = (-) It is irrelevant on the position of the 'sign'. NB If no sign is given, then read it as positive (+).
18 + 12 + 0 - 4 - 10 = 16
20 + 10 - 31 + 30 - 5 = 24
find the denomenator with is 30 10/30 9/30 the answer is 1over 3
10 - 5 + 14324 + 12 + 30 - 1000 = 13371
