Question

Ritin has 21/5 litres of lemonade of which he distributed 13/4 litre lemonade . how much lemonade left with him

Answer 1

Ritin has 21/5 lemonade and he distributed meaning he took away 13/4 liters of lemonade. Find a common denominator between 5 and 4. Since we know 5 times 4 is 20 the smallest common denominator so lets multiply 21/5 by 4 getting 84/20 and multiply 13/4 by 5 getting 65/20. Since both fractions have 20 as the denominator, subtract 84/20 by 65/20 and you get 19/20 liters of lemonade as your answer.

Answer is 19/20 liters of lemonade Ritin has left

Answer 2

`\large\begin{array}{I} \mathtt{Lemonade~ left = (21)/(5) - (13)/(4) =(21 * 4 - 13 * 5)/(20) = (84-65)/(20)= (19)/(20)~ litres} \end{array}`
