how do I work out this problem?19/20-(1/2-3/10)
With PEDMAS (or any of it's twins) you always start with what's inside the brackets. In this caseunknown said:how do I work out this problem?19/20-(1/2-3/10)
Brackets in fractions are used to indicate that the numbers within them should be treated as a single unit. This helps to avoid confusion and ensures that the correct operations are carried out when solving equations.
To simplify fractions with brackets, you must first apply the operations inside the brackets. Then, you can use the rules of fractions to simplify the expression further. Remember to always simplify the numerator and denominator separately.
No, brackets do not change the value of a fraction. They are used for grouping purposes and do not affect the actual value of the fraction. However, they can change the order of operations and therefore affect the final result.
When solving equations with fractions and brackets, you must first apply the operations inside the brackets. Then, use the rules of fractions to simplify the expression. Finally, you can solve for the variable using standard algebraic techniques.
No, it is not necessary to use brackets when working with fractions. However, they can be helpful in indicating the order of operations and avoiding confusion. It is ultimately up to personal preference and the complexity of the equation being solved.
