The mass of a coin : 2.2613 g
<h3>Further explanation </h3>
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:
algebraic forms separated by arithmetic operations
consists of one phrase (monomial) to many phrases (polynomial)
is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.
is a fixed value, can be a number
- 4. arithmetic operations ⇒ +, - , : , x
<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>
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](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B1%7D%7B100%7D%5Ctimes%20226.13~g%3D2.2613~g)
