I like to use an X diagram to solve problems like this. The constituent percentages are on the left, the desired mix is in the middle and the numbers on the diagonals are the difference between the mix and the constituent.
The numbers 6 and 24 here represent the ratio of 40% to 10% chocolate. That 6:24 ratio can be reduced to 1:4. The sum of those ratio units is 1+4 = 5, so each must represent (200 kg)/5 = 40 kg of chocolate.
The mix must consist of
40 kg of 40% fat chocolate 160 kg of 10% fat chocolate
Whole numbers are sometimes integers.
<h3>Further explanation</h3>
- The set of natural numbers (also called the set of counting numbers) is denoted by N:
- Natural numbers together with zero called are called whole numbers. The set of whole numbers is denoted by W:
- The set of natural numbers are not enough for all the number problems in everyday life. For example, natural numbers cannot be used to write some winter temperatures, since such temperatures may be less than zero i.e., negative numbers.
- The set of integers are the union of the set of negative numbers with the set of natural numbers and zero. The set of integers is denoted by Z:
- The set of negative integers is denoted by Z⁻:
- The set of positive integers is denoted by Z⁺:
- The set of non-negative integers are the set of all positive integers together with zero.
- The set of non-positive integers are the set of all negative integers together with zero.
Conclusion:
Whole numbers are sometimes integers because negative integers are not part of whole numbers. In other words, whole numbers are not fully integers.

Examples of integers around us:
- The height of an airplane flight typically between 31,000 and 38,000 feet.
- Ice melts at 0⁰C.
- This diver is swimming at -20 m.

Answer:
3.5
Step-by-step explanation:
If you multiply 3.5 for example by 2 (which is the number of gallons) you get 7 which is the cost (also a proportional relationship).
Answer:
The number is 17
Step-by-step explanation:
In summary, the central angle in a circle is the angle formed by two radius lines. An inscribed angle is the angle formed by points on the circle's circumference. There are a few key things to know about central and inscribed angles.
