Answer 1

Verified answer

1. 2 ⅖ + 3 3/10 + 1/4

= 2 + 3 = 5

⅖ + 3/10 + ¼

= .../20 + .../20 + .../20

=(20 ÷ 5 × 2)/20 + (20 ÷ 10 × 3)/20 + (20 ÷ 4 × 1)/20

= 8/20 + 6/20 + 5/20

= 14 + 5/20

= 19/20

= 5 19/20

2. 5 4/9 + 2 ⅖ + 5/12

= 5 + 2 = 7

4/9 + ⅖ + 5/12

= .../180 + .../180 + .../180

=(180 ÷ 9 × 4)/20 + (180 ÷ 5 × 2)/180 + (180 ÷ 12 × 5)/180

= 80/180 + 72/180 + 75/180

= (80 + 72 + 75)/180

= (152 + 75)/180

= 227/180

= 1 47/180

= 7 + 1 = 8

= 8 47/180

3. 3 ¾ + 3 ⅙ + ⅓

• 3 + 3 = 6

¾ + ⅙ + ⅓

= .../12 + .../12 + .../12

= (12 ÷ 4 × 3)/12 + (12 ÷ 6 × 1)/12 + (12 ÷ 3 × 1)/12

= 9/12 + 2/12 + 4/12

= (9 + 2 + 4)/12

= 15/12

= 1 3/12

= 1 1/4

= 6 + 1 = 7

= 7 ¼

4. 2 ½ + 3 ⅓ + 1 ¼

= 2 + 3 + 1 = 6

½ + ⅓ + ¼

= .../12 + .../12 + .../12

= (12 ÷ 2 × 1)/12 + (12 ÷ 3 × 1)/12 + (12 ÷ 4 × 1)/12

= 6/12 + 4/12 + 3/12

= 13/12

= 1 1/12

= 6 + 1 = 7

= 7 1/12

5. 2 ⅕ + ⅔ + 2 ¼

= 2 + 2 = 4

⅕ + ⅔ + ¼

= .../60 + .../60 + .../60

= (60 ÷ 5 × 1)/60 + (60 ÷ 3 × 2)/60 + (60 ÷ 4 × 1)/60

= 12/60 + 40/60 + 15/60

= 67/60

= 1 7/60

= 1 + 4 = 5

= 5 7/60
