Set up an equation 20=k(0.4)....to find k divide 20 by 0.4
You can solve this by convert mixed number(s) into improper fraction(s) 2. change both fractions to the equivalent fractions with the same denominator 3. omit denominators and write numerators as a ratio 4. simplify the ratio by dividing both numbers by the highest common factor.
209/2 is 104.5, add 0.5 to once and take away 0,5 once so your left with 104 and 105 then 104+105=209 and they’re integers which are consecutive. :))
