Given:
2/5 ÷ 8/5
Determine Corey's mistake when she wrote 5/2 x 8/5
Explanation:
We must take note that in dividing two fractions, we must take the reciprocal of the denominator, not the numerator. In Corey's case, she took the reciprocal of 2/5 which is 5/2 then multiply it with 8/5. She must focus on the denominator and not on the numerator. To correct the procedure, we will take tha reciprocal of 8/5 which is 5/8 then multiply it with 2/5
Solution:
= 2/5 ÷ 8/5
= (2/5)(5/8)
=2/8
= ¼
Final answer
= ¼
