What is a decimal in mathematics?

A decimal is a fraction expressed in a special form. It uses a decimal point to separate the whole number part from the fractional part.

How do you convert a fraction to a decimal?

To convert a fraction to a decimal, divide the numerator by the denominator. For example, $$\frac{1}{4} = 0.25$$ .

What is the second step in solving the equation $$2.6x + 14.2 = 19.92$$ ?

The second step is to divide both sides by 2.6 after subtracting 14.2 from both sides.

What is the purpose of checking your solution in an equation?

Checking your solution ensures that the value you found satisfies the original equation.

How do you check the solution of $$x = 4.2$$ in the equation $$-x^2 - 5.6 = -7.7$$ ?

Substitute 4.2 into the equation: $$-4.2^2 - 5.6 = -7.7$$ . If both sides are equal, the solution is correct.

What is the importance of understanding two-step equations?
