~ 2 3/4 - 3 1/3 : 2 1/2=….
~ 2 1/4 + 1 1/2 * 2 2/3

Answer 1

3/4 + 1/2 x 2/3

= 3/4 + (1/2 x 2/3)

= 3/4 + (1/1 x 1/3)

= 3/4 + 1/3

= 9/12 + 4/12

= 13/12

= 1 1/12

3 1/2 + 5 1/3 : 1 3/5

= 7/2 + (16/3 : 8/5)

= 7/2 + (16/3 x 5/8)

= 7/2 + (2/3 x 5/1)

= 7/2 + 10/3

= 21/6 + 20/6

= 41/6

= 6 5/6

2 3/4 - 3 1/3 : 2 1/2

= 11/4 - (10/3 : 5/2)

= 11/4 - (10/3 x 2/5)

= 11/4 - (2/3 x 2/1)

= 11/4 - 4/3

= 33/12 - 16/12

= 17/12

= 1 5/12

2 1/4 + 1 1/2 x 2 2/3

= 9/4 + (3/2 x 8/3)

= 9/4 + (1/1 x 4/1)

= 9/4 + 4/1

= 9/4 + 16/4

= 25/4

= 6 1/4
