Observe that
8² = 64
(1/1000)² = 1/1000000 = 0.00001
8² × (1/1000)² = 64 × 0.000001 = 0.000064
Then
(14 1/2)/(1 1/4) change both to improper fractions
(29/2)/(5/4) invert second function (or the denominator fraction) and multiply.
(29/2)*(4/5) multiply...
58/5 change improper fraction back to mixed fraction
11 3/5 or a decimal 11.6
Are you sure the equation does say 2X+16=(-1)?
