We have to multiply those numbers and to write it in the simplest form: 5 * 6/8 = 5 * 3/4 = 15/4 = 3 3/4. Another product is: 2 * 9/10 = 18/10 = 9/5 = 1 4/5. Then we will identify the 2 whole numbers between the product lies. Answer: For 15/4 ( equal to 3 3/4 ) those numbers are 3 and 4. For 9/5 (equal to 1 4/5 ) those numbers are 1 and 2.
