Question

On Monday,Lyn Johnson worked for 3 1/4 hours. Tuesday thursday, she worked for 4 1/3 hours each day. On friday, she worked for 6 1/2 hours. How many hours total did she work during the five days?

Answer 1

22 3/4 hours

Explanation:

monday + tuesday + wednesday + thursday + friday

3 1/4 + 4 1/3 + 4 1/3 + 4 1/3 + 6 1/2

the common denominator is 12

3 1/4 *3/3 = 3 3 /12

4 1/3 * 4/4 = 3 4/12

6 1/2 * 6/6 = 6 6/12

3 3 /12 + 4 4/12 + 4 4/12 + 4 4/12 +6 6/12 =

(3+4+4+4+6) + (3 +4+4+4+6)/12

21 +(21/12) we can simplify 21 /12

21 + 12/12 + 9/12

21 + 1 + 9/12

22 + 9/12 we can simplify 9/12 by dividing top and bottom by 3

22 3/4
