Express 3 1 4 % as decimal.

Given that convert 3 1 4 % into decimal. First, we shall convert the mixed fraction into improper fraction. 3 1 4 = 3 × 4 + 1 4 = 13 4 To convert a percentage into a decimal, first convert the percentage into a fraction by replacing the % sign with 1 100 then convert the fraction into a decimal. x y % = x y 100 = 0 . x y Thus, we get 3 1 4 % = 13 4 % = 13 4 × 100 = 13 3 . 25 4 1 × 100 = 3 . 25 100 = 0 . 0325 Hence, the obtained decimal is 0 . 0325 .

Find the value of 6 1 4 % of 25 kg .

Given that find the value of 6 1 4 % of 25 kg . Let us convert the given mixed fraction into improper fraction. 6 1 4 % = 25 4 % To finding a percentage of a given quantity, change the percentage into fraction and fraction and multiply by the given quantity. Thus, x % of a given quantity = x 100 × given quantity. Now, let us apply this formula to find the value of the given quantity. 6 1 4 % of 25 kg = 25 4 % of 25 = 25 4 × 100 × 25 kg = 25 × 25 4 × 100 kg = 25 16 kg = 1 9 16 kg Hence, the obtained value is 1 9 16 kg .
