How do you put improper fraction as a mixed number in simplest form?
Suppose n/d is an improper fraction where, by definition, n > d.Divide n by d to give a quotient q and a remainder r. Then the equivalent mixed number is q r/d.
What is the definition of respective weights as a math term?
"Respective" means "in that order". So, for example, weights of 1 Newton, 2 N and 3 N at points p q and r respectively, menas a weight of 1 N at point p, 2 N at q and 3 N at r.
How can you get an equivalent fraction?
With a given fraction N/D, where N & D are integers [D not equal to zero]. Take any nonzero integer (p). Multiply both N and D by p:N/D = (N*p)/(D*p)Also, if N & D have any common factors {call it q}, then dividing N & D by q will give an equivalent fraction. So if the fraction is 6/16, let p = 3: the new fraction is 18/48. Since 6 and 16 have a common factor of 2, you can divide both 6 & 16 by 2 and get 3/8, which is equivalent to 6/16 and 18/48.Here are some more examples: a fraction equivalent to 1/2 would be 7/14. to reduce a fraction, find the Greatest Common Factor between the two sides. for example, if you were reducing 36/60, the greatest common factor between 36 and 60 would be 12. 36 divided by 12 is 3, and 60 divided by 12 is 5. so, a fraction equivalent to 36/60 would be 3/5. 3 and 5 cannot reduce any further.
Which shape has a rotational symmetry of 3 and is not a triangle?
Any polygon with 3n sides (n > 1) where every nth side is equal and every nth angle is equal: that is the sides and angles repeat in sets of n. For example a hexagon (n = 2) with sides of length x,y,x,y,x,y and angles of P,Q,P,Q,P,Q.
