Question

A pastry chef creates a dessert with two layers. The first layer is 5/6 of an inch thick, and the second layer is 3/4 of an inch thick. How thick is the dessert?
Which statements are true about this problem? Check all that apply.

1.) 5/6 is closer to 3/4 than 1.
2.) The solution can be found by adding the fractions.
3.) A common denominator could be 12.
4.) The solution is greater than 1 inch.
5.) The total thickness of the dessert is less than 1 inch.

Answer 1

For this case we have to find the thickness of the dessert, we can upload the fractions:

$\frac{5} {6} + \frac {3} {4} = \frac {20 + 18} {24} =$

$\frac {38} {24} = \frac {19} {12} = 1.58$

According to the statements we have:

$\frac{5}{6}=0.83\\\frac{3} {4} = 0.75$

$\frac {5} {6}$ is closer to $\frac {3} {4}$

The solution is found by adding the fractions.

A common denominator is 12.

The solution is larger than 1 inch.
