Ms. Geiger made 100 cupcakes. 60/100 were chocolate, 2/10 were vanilla, and the rest were red velvet. What fraction of the cupcakes were red velvet?

2/10

Step-by-step explanation:

Ms. Geiger made 100 cupcakes.

a) Number of chocolate

60/100 were chocolate

= 60/100 × 100 = 60 chocolate cup cakes

b) Number of vanilla

2/10 were vanilla

Hence:

2/10 × 100 = 20 vanilla cup cakes

c) the rest were red velvet.

Number rod red velvet = 100 - (60 + 20)

= 100 - 80

= 20 velvet cupcakes

What fraction of the cupcakes were red velvet?

Converting to fraction

Number of velvet cupcakes/Total number of cakes

= 20/100

= 2/10
