Fill in the blanks of the following: `a/3=b/4=c/7=(a-2b+3c)……=………/(6-8+14)`

Fill in the blanks: a/3=b/4=c/7=(a-2b+3c)/……=………/(6-8+14)

Fill in the blanks: a/3=b/7=(4a-9b)/(square)

Using the property a/b=ak/bk fill in the blanks subsituting proper numbers in the following. 9/14=4.5/….=…./42=…./3.5

Fill in the blanks to prove that b is the geometric mean of a and c, if (a-b+c)/(ab+c^2) =1/(b+c)

If A = {1, 2, 3, 4}, B = {3, 4, 5, 6}, C = {4, 5, 6, 7, 8} and universal set x = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then verify the following: B = (A nn B) uu (A' nn B)

If A = {1, 2, 3, 4}, B = {3, 4, 5, 6}, C = {4, 5, 6, 7, 8} and universal set x = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then verify the following: A = (A nn B) uu (A nn B')
