1.)
2 1/3 + 1 1/5 – 11/15
= 7/3 + 6/5 – 11/15
= 35 + 18 – 11/15
= 53 – 11 /5
= 42 / 5
= 8 2/5
2.)
5/8 – 1/6 + 2 1/4
= 5/8 – 1/6 + 9/4
= 15 – 4 + 54/24
= 11 + 54 / 24
= 65 / 24
= 2 17/24
3.)
3 1/3 ÷ 0,4
= 10/3 ÷ 2/5
= 10/3 x 5/2
= 5/3 x 5/1
= 25/3
= 8 1/3
4.)
3/10 ÷ 0,25
= 3/10 ÷ 1/4
= 3/10 x 4/1
= 12/10
= 1,2
