answer is here..........

Answer 2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

7 / 4 ÷ 28 = 7/4 * 1/28 = (7)/(4*28) = 7/112 = 0.0625

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

What is done in the answer? In the answer, 7/4 ÷ 28 can be written as 7/4 * 1/28 because if in place of the division sign, we place the multiplication sign, then, we need to take the reciprocal of the number which is after the division sign. Since the reciprocal of 28 is 1/28, 7/4 ÷ 28 can also be written as 7/4 * 1/28; which can further be written as (7)/(4*28) because 7*1 = 7. Since 4*28 = 112, (7)/(4*28) = 7/112, or it can be written as 0.0625 by division also.
