DochEvi [55]

Answer:

2/15 fraction of money is spend to buy magazine.

Step-by-step explanation:

Total Money given by Evan's uncle = $30

Money spent by Evan to buy magazine = $4

Fraction of money spend on magazine =  Money spent by Evan to buy magazine  ÷ Total Money given by Evan's uncle

2/15  of Total Money given by Evan's uncle = (2/15 )× 30 = 2 × 2 = 4

so $4 represents  2/15  of $30 , hence our solution is correct .
