A man spent 2/5 of his salary on food and 1/4 on transport. What fraction of the salary was left
A man spent two-third of his monthly wages on his car and one-quarter on food.If he spent #5500 altogether,how much does he earn in a month?
7/20 is answer
13/20
I don’t understand
1 plus 1
Let the overall money he had be 1 hence we dealing with fractions. Therefore 1- 2/5-1/4 is 7/20. Hence the money left of his salary in fraction is 7/20
Yes, that is correct! Good job!
I don't understand either
To find the fraction of the salary that was left, we need to subtract the fractions spent on food and transport from the whole salary.
Let's represent the whole salary as 1.
The fraction spent on food is 2/5, and the fraction spent on transport is 1/4.
To find the fraction left, we subtract the fractions spent on food and transport from 1:
1 - (2/5 + 1/4)
First, we need to find a common denominator for 5 and 4, which is 20.
Converting 2/5 to 4/20 and 1/4 to 5/20, we have:
1 - (4/20 + 5/20)
Now, we can combine the fractions:
1 - (9/20)
To subtract fractions, we need to have a common denominator, which in this case is 20.
Subtracting the numerators, we get:
(20 - 9) / 20 = 11/20
Therefore, 11/20 fraction of the salary was left after spending on food and transport.
The Common denominator would be 5x4=20
So making each an equivalent fraction gives 2/5=8/20 and you do the 1/4=
Then you have the entire salary of 20/20 and you take away both equivalent fractions : )
20/20 - 8/20 - ....
= salary left : )
