The answer to this question is x=3
Answer:
8/45 or 0.177...... (the seven continues forever).
Step-by-step explanation:
8/9 ÷ 5
First, turn 5 into a fraction. That will be 5/1
8/9 ÷ 5/1
When you're dividing fractions, you flip the second fraction and turn the division sign to a mutiplication sign
8/9 ÷ 1/5
8/9 * 1/5
Now you multiply. We will multiply the numerator and then the denominators through since there are no common factors.
8 * 1/9 * 5
8/45
