4. Bell Ringer Problem #1 Lcm(10,18) Enter into calculator MATH NUM → lcm Enter denominators

5. Bell Ringer #2 Convert 3.4ft to inches (12in = 1 ft)

6. Bell Ringer #2 Step 1: Place 3.4 ft over 1 3.4 ft 1

7. Step 2: insert your multiplication sign and draw your second fraction. Place the given units at cross angles and the desired unit (inches) on top 3.4 ft. ___in 1 ft

8. Step 3: Write the relationship between inches and feet (1 foot = 12 inches) 3.4 ft. 12in 1 1ft

9. Step 4: Multiply Straight across and divide if you need to 3.4 ft. 12 in = 14.4 in = 40.8 inches 1 1 1

10. Bell Ringer Problem #3 Add 5 3 + 8 2 in your calculator. 4 7 Give me your answer as a improper fraction and a mixed number.

11. Step 1: REMEMBER THE WORD “AND” MEANS ADDITION. SO…….. 5 3 would be said as 5 “and” 3 4 4 and 8 2 would be said as 8 “and” 2 7

12. So……you would enter the problem in the calculator exactly as follows: -(5 + 3/4) + (8 + 2/7) -Hit enter (you get a decimal) -Press Math, Enter, Enter -Now you have an improper fraction -Convert to a mixed number

13. Bell Ringer Problem #4 Multiple choice: What number could I add to the numerator and denominator of 7 to get 1? 10 2 a)4 b)2 c)-4 d)6

14. Step 1: Work backwards and take each answer choice and add to the numerator and denominator and see if you get 1 or 2 an equivalent fraction.

15. For example: 7 + - 4 = 3 10+ - 4 6 Does this fraction simplify to 1? Yes!! 2 So, -4 is the correct answer choice
