1/8th part of a pencil is black, half of the remaining is white. If the remaining part is blue and length of this blue part is 3 1/2cm, then find the length of the pencil ?

The expression (11.98 x 11.98 + 11.98 x x + 0.02 x 0.02) will be a perfect square for x equal to:

[ .6 x .6 x .6 x .4 x .4 x .4 + 3 x .6 x .4 x (.6 + .4 )] = ?

When 0.36 is written in simplest form, the sum of the numerator and the denominator is :

If 1.5x = 0.04y, then the value of ( (y - x) / (y+x) ) is :

The numerator of a fraction is 3 less than its denominator. If we add 10 to the numerator, the fraction is increased by 1 3/7. What was the original fraction?
