Question

Which of these are mathematical laws that help us solve numerical problems? A. decimals B. graphs C. formulas D. percentages E. fractions

Answer 1

The correct answer is C) Formulas

Explanation:

Formula is a problem-solving technique that students can use to find answers to math problems involving geometry, percents, measurement, or algebra. To solve mathematical numerical problems, one should use appropriate formula and substitute data in the correct places of a formula to find the required results. If there is a slight mistake in the formula everything goes wrong.

Answer 2

Hello!

The answer is C. formulas

Why?

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!
