Problem 22 - Elementary Algebra

Question

For the following problems, use the order of operations to find each value. $$21 \div 7 \div 3$$

Step-by-Step Solution

Answer

Answer: 1

Step 1: Division left to right

Since the given expression contains only division, we will perform the operations from left to right. $$ 21 \div 7 \div 3 $$

Step 2: Perform the first division

Divide 21 by 7: $$ \frac{21}{7} = 3 $$ Now our expression becomes: $$ 3 \div 3 $$

Step 3: Perform the second division

Divide 3 by 3: $$ \frac{3}{3} = 1 $$ So the value of the given expression is 1.
