Answer 1

1.4 12/16+4 2/4-3 2/8=76/16+18/4-26/8= 76/16+ 72/16- 52/16=148/16-52/16=96/16

Answer 2

1). 4 12/16 + 4 2/4 - 3 2/8 =
76/16 + 18/4 - 26/8 = 76/16 + 72/16 - 52/16 = 96/16= 6

2). (6 3/37 x 2 1/3) ÷ 1 2/4 =
(225/37 x 7/3) ÷ 6/4 =
525/37 x 4/6 = 2100:2/222:2 = 1050/111 = 9 51/111

3). (5 3/6 ÷ 2 1/2) - 2/4 =
(33/6 x 2/5) - 2/4 =
33/15 - 2/4 = 132/60 - 30/60 = 102:2/60:2 = 51/30 = 1 21/30 = 1 7/10

4). 7 30/40 = 7 15/20 = 155/20 x 100% = 775%

5). 8 3/4 + 0,24 + 75% =
35/4 + 24/100 + 75/100 = 875/100 + 24/100 + 75/100 = 974/100= 9 74/100

6). 6 5/6 + 2/5 + 0,25 =
6,833 + 0,4 + 0,25 = 7,483

7). 5 7/20 - 0,30 + 2 3/4 =
5,35 - 0,30 + 2,75 = 7,8

Semoga membantu :)
