Question

2. Mr. Penman had 2/3 liter of salt water. He used 1/5 of a liter for an experiment. How much salt water does Mr. Penman have left?

Answer 1

7/15

Explanation:

Simplify the terms:

• 
  `(2)/(3)=(10)/(15)`

• 
  `(1)/(5)=(3)/(15)`

Combine the terms:

• 
  `(10)/(15)-(3)/(15)=(7)/(15)`

Therefore, the total of salt water would be left would be 7/15..
