Celia has some cakes.

Vadim26 [7]

The carrot cakes are the fraction of the cake given by $1 - \frac{6}{7}$ multiplied by $\frac{1}{3}$

The fraction of the cakes that are carrot cakes is $\underline {\dfrac{1}{21}}$

<h3>How are the cakes evaluated as fractions?</h3>

The fraction of the cake that are chocolate cake = $\dfrac{2}{3}$

The fraction of the remaining cake that cheesecakes = $\dfrac{6}{7}$

The rest of the cakes = carrot cakes

Required:

The fraction of the cake that are carrot cakes

Solution:

The fraction of the cakes that are not chocolate cake = $1 - \dfrac{2}{3} = \mathbf{ \dfrac{1}{3}}$

The fraction of the remaining cakes that are cheesecake = $\dfrac{6}{7} \times \dfrac{1}{3} = \mathbf{ \dfrac{6}{21}}$

The fraction of the cake that are carrot cake = $\dfrac{1}{3} - \dfrac{6}{7} \times \dfrac{1}{3} = \mathbf{\dfrac{1}{21}}$

The fraction of the cakes that are carrot cake is $\underline{\dfrac{1}{21}}$

121 minutes to 3 hours

Anastaziya [24]

For this case we must do a conversion from minutes to hours.

By definition we have to:

1 hour equals 60 minutes

So, through the rule of three we have:

1h -------------> 60 min

x --------------> 121 min

Where "x" represents the amount of hours equivalent to 121 minutes.

$x = \frac {121 * 1} {60} = 2.0167$

Thus, 121 minutes equals 2.0167 hours

Answer:

121 minutes equals 2.0167 hours
