QuestionAdd parentheses to make true. 36÷93=636 \div 9-3=6

Studdy Solution

STEP 1

What is this asking? We need to figure out where to put parentheses in the equation 36÷93=636 \div 9 - 3 = 6 to make it true! Watch out! Remember the order of operations—PEMDAS/BODMAS—it's super important here!

STEP 2

1. Try Parentheses Around the Division
2. Try Parentheses Around the Subtraction

STEP 3

Let's try putting parentheses around 36÷936 \div 9.
This gives us (36÷9)3=6(36 \div 9) - 3 = 6.

STEP 4

Inside the parentheses, we have 36÷936 \div 9, which equals **4**.

STEP 5

Now, our equation is 43=64 - 3 = 6.

STEP 6

43=14 - 3 = 1.
So, we have 1=61 = 6, which is **not true**.
This means the parentheses *don't* go around the division.

STEP 7

Let's try putting parentheses around 939 - 3.
This gives us 36÷(93)=636 \div (9 - 3) = 6.

STEP 8

Inside the parentheses, we have 939 - 3, which equals **6**.

STEP 9

Now, our equation is 36÷6=636 \div 6 = 6.

STEP 10

36÷6=636 \div 6 = 6.
So, we have 6=66 = 6, which is **absolutely true**!

STEP 11

Putting the parentheses around 939 - 3 makes the equation true.
So, the correct equation is 36÷(93)=636 \div (9 - 3) = 6.
