okay so 2/5 is 2 parts of the 5 and that costs 12 so you would do 12÷2 which is 6 to and that's 1/5 of his allowance so now all you have to do is do 6 (1/5) times 5 and that gets you 30 which is his allowance. hope this helps :)
Answer:
Eric allowance is $30
Step-by-step explanation:
To solve this problem, we will follow the steps below:
Let x be Eric allowance
2/5 of x = $12
[tex]\frac{2}{5}[/tex] × x = $12
[tex]\frac{2x}{5}[/tex] = $12
Multiply both-side of the equation by 5
[tex]\frac{2x}{5}[/tex]×5 = $12×5
At the left-hand side of the equation 5 will cancel-out 5
2x = $60
Divide both-side of the equation by 2
[tex]\frac{2x}{2}[/tex] = [tex]\frac{60}{2}[/tex]
(On the left-hand side of the equation, 2 at the numerator will cancel-out 2 at the denominator while on the right-hand side of the equation, 60 will be divided by 2)
x = $30
Therefore, Eric allowance is $30
