Answer 1

1 )... 1⅓ + 3/5 =4/3+3/5=20/15+9/15=29/15=1i14/15

2 i 5 / 6 + 1⅜ =17/6+11/8=68/24+33/24=101/24=4i5/24

5/9 + 5/6 =10/18+15/18=25/18=1i7/18

1 i 7/10 + 2 i 3/4 =17/10+11/4=34/20+55/20=89/20=4i9/20

7/8 + 6 i 3/4 =7/8+27/4=7/8+54/8=61/8=7i5/8

 

2 ) .. 6 i 7/9 - 2/3 =61/9-2/3=61/9-4/9=57/9=6i3/9=6i1/3

1½ - 6/7 =3/2-6/7=21/14-12/14=9/14

4¼ - 2⅚ =17/4-17/6=51/12-34/12=17/12=1i5/12

6 i 5/12 - 7/9 =77/12-7/9=231/36-28/36=203/36=5i23/36

 

3) .. ¾ × 2/9 =1/2*1/3=1/6

1 i 2/3 × 9/10 =5/3*9/10=3/2=1i1/2

5 i 3/16 × 8 =83/16*8/1=83/2=1i1/2

12 × 3 i 3/4 =12/1*15/4=3/1*15/1=45

 

4) .. 3/5 ÷ 7/10 =3/5*10/7=3/1*2/7=6/7

2/3 ÷ 3/4 =2/3*4/3=8/9

5/6 ÷ 3 =5/6*1/3=5/18

2/11 ÷ 16/33 =2/11*33/16=1/1*3/8=3/8

3 i 5/7 ÷ 2/3 =26/7*3/2=13/7*3=39/7=5i4/7

1 i 1/3 ÷ 2 i 2/5 =4/3*5/12=1/3*5/3=5/9

7 i 1/5 ÷ 8 =7i1/5*1/8=36/5*1/8=36/40=9/10

 

Answer 2

1).. a 1 1/3 + 3/5  = 1  1/15 + 9/15 = 1  10/15

b  2 * 5/6 + 1 3/8 = 2*5/6 + 1 3/8 = 40/6 * 1  39/8 = 40/24 + 1  39/24  = 1  49/24  = 3 1/24

c 5/9 + 5/6 = 20/26 + 30/26 = 50/26 = 1 24/26

d 1* 7/10 + 2* 2/4  = 1*7/10 + 2*3/4  = 34/40= 34/40 + 60/40 = 96/40 = 2 16/40

e 7/8 + 6 * 3/4 = 7/8 * 6*3/4 = 7/16 + 18/16 = 25/16 = 1 9/16
