Question

a baker decorates 42 cupcakes in 30 minutes she decorates cupcakes at a constant rate. how many cupcakes can the baker decorate per minute

Answer 1

Answer:

Number of cake decorate in 30 min = 42

Number of cake decorate in 1 min = 42/30 =1.4

Answer 2

Answer: The baker can decorate 1.4 or 1 1/3 of cupcakes in a minute.

Step-by-step explanation: 42 cupcakes in 30 minutes so if you divide 42 cupcakes in 30 groups you get 1 in each group and 12 left so if make 30 in 3 it makes 4 in each group but it is 30 so you make the four in to a 0.4 or 1/3 which is 1.4.

You can also multiply if you make 1.4 into 14 x 3 = 42 same as 1.4 x 30 = 42 so the answer is 1.4.
