What is 6 and 3/4 add 1 and 6/7? Write answer as a mixed number thanks! Next Question: What is 9 and 1/5 takeaway 2 and 7/8? Write the answer as a mixed number ok! Next Question : What is 4 and 1/3 times 1 and 3/4 ? Write the answer as a mixed number ok thanks! Last question: What is 6 and 6/7 divided by 3 and 2/3 ? Write the answer as a mixed number!!!!! Ok thanks! Try and answer all the questions ok !!!!!!!!!

1). 6 3/4+1 6/7

= 27/4 + 13/7

= ((27 × 7) + (13 × 4)) / (4 × 7)

= (189 + 52) / 28

= 241/28

= 241/28

= 8 17/28

2). 9 1/5- 2 7/8

= 46/5 − 23/8

= ((46 × 8) − (23 × 5)) / (5 × 8)

= (368 - 115) / 40

= 253/40

= 253/40

= 6 13/40

3). 4 1/3* 1 3/4

= 13/3 × 7/4

= (13 × 7) / (3 × 4)

= 91/12

= 91/12

= 7 7/12

4). 6 6/7 ÷ 3 2/3

= 48/7 ÷ 11/3

= (48 × 3) / (11 × 7)

= 144/77

= 144/77

= 1 67/77

Hope I helped!
