They baked 2 dozen because each dozen is 12 so one did 17 + another did 11 = 28 and divide it by 12 get. 2 dozens.
Using proportions, it is found that:
1. 1.4 groups of 5/7 are in 1.
2. The result of 8 divided by 5/7 is of 11.2.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Applying a rule of three, to find how many groups of 5/7 are in 1, we divide 1 by 5/7, hence:
1/(5/7) = 7/5 = 1.4.
Hence 1.4 groups of 5/7 are in 1.
Following the same pattern, for item 2, we have that:
8/(5/7) = 8 x 7/5 = 56/5 = 11.2.
The result of 8 divided by 5/7 is of 11.2.

Hi
7√8*4√5
= 56√10
I hope that's help and sorry for late answer ^...^
The statement is false.
Explanation:
An exterior angle and its adjacent interior angle fall together on a straight line to form a linear pair.
Because the sum of adjacent angles on a straight line is 180⁰ (not 360⁰), the statement is false.
