Mr brown spends his monthly salary of $1440. He spends on food 1/4, on transport 30%, on bill 20% and on rent? Find what fraction of his monthly income does he spend on rent show working
First, we need to calculate how much Mr. Brown spends on food, transport, and bills.
Food: $1440 x 1/4 = $360
Transport: $1440 x 30% = $1440 x 0.30 = $432
Bills: $1440 x 20% = $1440 x 0.20 = $288
Total spent on food, transport, and bills = $360 + $432 + $288 = $1080
Now, to find the amount spent on rent, we can subtract the total spent on food, transport, and bills from the monthly salary.
Amount spent on rent = $1440 - $1080 = $360
Now, we need to find what fraction of his monthly income Mr. Brown spends on rent.
The fraction is calculated by dividing the amount spent on rent by the total monthly income.
Fraction spent on rent = $360 / $1440
To simplify the fraction, both the numerator and denominator can be divided by 360.
Fraction spent on rent = 1/4
Therefore, Mr. Brown spends 1/4 of his monthly income on rent.
