Question

Si 100 monedas tienen una masa total de 226.13g. Cual es la masa de una moneda

Answer 1

The mass of a coin : 2.2613 g

Further explanation  

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.  

The main composition of algebraic expressions are:  

• 1. phrases  

algebraic forms separated by arithmetic operations  

consists of one phrase (monomial) to many phrases (polynomial)  

• 2. variables  

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.  

• 3. constants  

is a fixed value, can be a number  

• 4. arithmetic operations ⇒ +, - , : , x

If 100 coins have a total mass of 226.13g. What is the mass of a coin

We can make this statement in the form of an algebraic equation :

100 coins=226.13 g

then the mass of a coin :

$\tt \dfrac{1}{100}\times 226.13~g=2.2613~g$
