1/12 of john's salary was spent on electricity and 2/6 of his salary went to pay rent. How much does he have left?
1/12 + 2/6 = 5/12 spent
so, how much was unspent?
total fraction = 1/1- 1/12 + 2/6.
= 1- 5/12
=7/12
To find out how much John has left after paying for electricity and rent, we need to first determine the fractions of his salary that were spent on each expense.
Given that 1/12 of his salary was spent on electricity and 2/6 of his salary went towards rent, let's simplify these fractions to have a common denominator. Since 1/12 is equivalent to 2/24 (by multiplying the numerator and denominator by 2), we can compare it with 2/6.
Comparing these fractions, we see that 2/6 is equivalent to 8/24 (by multiplying the numerator and denominator by 4). Now, we have two fractions:
- 2/24 spent on electricity
- 8/24 spent on rent.
To calculate the total amount spent on electricity and rent, we add these fractions together:
2/24 + 8/24 = 10/24.
Now, to determine how much of John's salary is left, we need to subtract the amount spent (10/24) from his total salary (1 whole, which can be represented as 24/24):
24/24 - 10/24 = 14/24.
Therefore, John has 14/24 of his salary left after paying for electricity and rent.
