We start by solving the exercise in the numerator and then solve the exercise in the denominator.
We know that multiplication and division operations come before addition and subtraction operations, so first we will divide 15:3 and then multiply the result by 2:
The result of the numerator is 2 and now we will solve the exercise that appears in the denominator.
It is known that according to the rules of the order of operations, the exercise that appears between parentheses goes first, so we first solve the exercise
Now, we solve the division exercise:
The result we get in the denominator is 2.
Finally, divide the numerator by the denominator:
1
\( 100+5-100+5 \)
A fraction bar acts like grouping symbols! You must complete all operations in the numerator and denominator before dividing. Think of it as (numerator) ÷ (denominator).
Yes! Both division and multiplication have the same priority level, so you work left to right. So 15÷3×2 becomes 5×2 = 10, not 15÷6.
Remember PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). Write it out step by step!
Substitute your result back into a calculator or work backwards. Here: , so if our answer is 1, then 1×2 should equal 2 ✓
Because both the numerator and denominator equal exactly 2! When you divide equal whole numbers, you always get 1. No decimals needed here.
