2⅓·6:2⅙=

2¼·8-3½:2⅙=

3¼:¼+2½·⅕=

(12⅓-½)·9=

2½·3⅓+2½:1¼

(7⅔-5⅚):1⅓

Answer 1

2⅓·6:2⅙=7/3 *6:13/6=42/3 * 6/13=84/13= 6 6/13

2¼·8-3½:2⅙=9/4*8 - 7/2 :13/6=18- 7/2 *6/13=18 - 21/13=18 - 1 8/13= 17 13/13-1 8/13=16 5/13

3¼:¼+2½·⅕=13/4* 4/1 + 5/2* 1/5=13+1/2= 13 1/2

(12⅓-½)·9=(37/3 -1/2)*9= ( 74/6 - 3/6) * 9= 73/6 * 9= 219/2=109 1/2

2½·3⅓+2½:1¼=5/2*10/3 + 5/2:5/4=25/3+5/2*4/5=8 1/3+ 2= 10 1/3

(7⅔-5⅚):1⅓=(23/3- 35/6):4/3=(46/6 -35/6)*3/4=9/6 * 3/4=9/8=1 1/8

 

Answer 2

1. 7/3 x 6 : 13/6 = 14 x 6/13= 84/13= 6 6/13
2. 9/4 x 8 - 7/2 x 6/13 = 18 - 21/13 = 18 - 1 8/13 = 16 5/13

3. 13/4 x 4 + 5/2 x 1/5=  13 + ½ = 13½
4. ( 12 2/10 - 5/10) x 9= 11 7/10 x 9= 105,3
5. 5/2 x 10/3 + 5/2 x 4/5= 25/3 + 2 = 10⅓
6. ( 7 4/6 - 5 5/6) : 1⅓= 1 5/6 x 3/4 = 11/8= 1 3/8
