Answer:
Step-by-step explanation:
-Given that 5/7 chocolates were bought and 1/5 of them had sprinkles.
-We multiply the fraction that had sprinkles by the total of chocolate cakes to determine the number that had sprinkles.
-Let x be the total number of cupcakes:
[tex]Chocolate\ cakes=\frac{5}{7}x\\\\Sprinkles=\frac{5}{7}x\times \frac{1}{5}\\\\=\frac{1}{7}x[/tex]
Hence, a [tex]\frac{1}{7}[/tex] of the total cakes bought had sprinkles.
