Mr. Penman has 7/15 liter of salt water left
- The liter of salt water Mr penman has is 2/3
- The liter of salt used for an experiment is 1/5
Further Explanation
This question is a number problem that deals with fractions and you should use BODMAS to derive a solution to it.
To get the total fraction of the liters of salt that is left, then you will have to subtract the liter of salt he has from the liter of salt used for an experiment.
This implies 2/3-1/5.
To further solve this fraction, you have to find the smallest number that can divide the denominators (3 and 5) which is 15.
Now you should divide the denominators with 15 and also multiply the answers you derived by the numerators.
Therefore,
= 2/3-1/5
= 10/15-3/15
=7/15
The final answer is 7/15, which means Mr. Penman has 7/15 liter left.
The values above are fractions. They are rational numbers. There are 2 important parts of fractions, they are numerator and denominator. The numerator represents the top number in the fraction while the denominator is the below number in a fraction.
The rule of BODMAS was also used in solving this question, it is a short word for Bracket, Of, Division, Multiplication, Addition, subtraction
