Solve the following equation:
?
Let's rewrite the exercise in a more familiar equation form:
First, let's solve the part in parentheses:
Now we should obtain the exercise:
Finally, let's write the exercise as a fraction:
Solve the following exercise:
\( 12+3\cdot0= \)
Because of the order of operations (PEMDAS)! The parentheses around (42 + 7) mean you must add those numbers first. If you divide by 42 first, you're changing the entire meaning of the problem.
Let's check if we can! Since 9 = 3² and 49 = 7², they share no common factors. So is already in simplest form.
Follow PEMDAS: Parentheses first, then Exponents, then Multiplication and Division from left to right, finally Addition and Subtraction from left to right. Here, the parentheses tell you to add 42 + 7 first!
That's exactly the same thing! The fraction bar acts like a division sign, and everything in the denominator is like being in parentheses. Both and 9 ÷ (42 + 7) mean the same thing.
Since 9 < 49, this fraction is already less than 1, so it can't be written as a mixed number. Mixed numbers are only for improper fractions where the numerator is larger than the denominator.
