Which of these are mathematical laws that us solve numerical problems? a. decimals b. graphs c. formulas d. percentages e. fractions

The answer is C. formulas

Formulas are laws o conditions that help us when we are solving numerical problems, we use them to relate number/variables in order to found equivalence between what we are calculating and the information we have.

A formula can include constants, variables and always contain an equality, this last one will help us to establish the needed equivalence to solve numerical problems.

Discarding the other given options:

A. decimals: Incorrect, decimals are a type of number which is not whole numbers.

B. graphs: Incorrect, graphs are graphical tools that we can use to show information or data.

D. percentages: Incorrect, percentages are used to show numerical information as a fraction of 100 units.

E. fractions: Incorrect, like decimals, fractions are a type of number which is not whole numbers, fractions are represented by a division of a number into another, representing just a part of a determinate whole number.

Have a nice day!
