Question

noah spends 1/4 of his monthly take home pay on rent and 1/5 on a car payment. what fraction of his monthly take home pay does he have left?

Answer 1

`\text {Fraction of his money left = } 1 - (1)/(4) - (1)/(5)`


`\text {Fraction of his money left = } (20)/(20) - (1 * 5)/(4 * 5) - (1 * 4)/(5 * 4)`


`\text {Fraction of his money left = } (20)/(20) - (5)/(20) - (4)/(20)`


`\text {Fraction of his money left = } (20 - 5 - 4)/(20)`


`\text {Fraction of his money left = } (11)/(20)`
