Answer 1

1.
`6 (3)/(4)+1 (6)/(7):6+1=7. [tex] (3*7)/(4*7)= (21)/(28) \ and \ (6*4)/(7*4)= (24)/(28) \\` Add:
`(21)/(28)+ (24)/(28)= (45)/(28) \\`
`Answer:\boxed{7 (45)/(28)} \\` 2.
`9 (1)/(5)-2 (7)/(8):9-2=7. [tex] (1*8)/(5*8)= (8)/(40) \ and \ (7*5)/(8*5)= (35)/(40) \\` Subtract:
`(35)/(40)- (8)/(40)= (27)/(40) \\` Answer:
`\boxed{7 (27)/(40)} \\` 3.
`4 (1)/(3)*1 (3)/(4):4*1=4.[tex] (1*4)/(3*4)= (4)/(12) \ and \ (3*3)/(4*3)= (9)/(12) \\` Cross Multipy:
`(4)/(12)* (9)/(12)= (9)/(36) \\` Simplify:4 \frac{9}{36}=4 \boxed{3}{12}=4 \boxed{1}{4}
`\\ Answer:\boxed{4 (1)/(4)} \\` 4. 6 \frac{6}{7}÷3 \frac{2}{3}:6÷3=3.
`(6*2)/(7*2)= (12)/(14) \ and \ (3*7)/(2*7)= (21)/(14) \\` Multiply:
`(12)/(14)* (21)/(14)= (252)/(14) \\` Simplify:
`3 (252)/(14)=3 (18)/(1) \\` Answer:
`\boxed{3 (18)/(1)} \\`

Answer 2

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!
