Ok this equation is 20 = 0.004 x N, yes? Rearrange for the variable 'N' to get 20/0.004 = N, N = 5000. Not hard.

1*20 = 20 Thus n = 20
Let the unknown number be n.Then 20 x n = 177 : so n = 177 ÷ 20 = 8.85 or 817/20.
Per cent or percentage equates to a hundredth. So, 7.75 = n x 20/100 n = 7.75 x 100/20 = 7.75 x 5 = 38.5. 20% of 38.5 is 7.75
x = 15 - N.
n = 5
