tolong dijawab matematika SD ok

1/3 + 2 4/7 + 5/6
=1/3 + 18/7 + 5/6
=14 / 42 + 108 / 42 + 35 / 42
=122 / 42 + 35 / 42
=157 / 42
=3 3/7

1,74 + 68 % + 2 3/8
=87/50 + 17 / 25 + 19/8
=348 / 200 + 136/200 +475 / 200
=959 / 200



5/6 - 2/9
=45 / 54 - 12 / 54
=33 / 54 (d)

3,4 - 1,52
=1,88 (c)

4,2 + 2,63 - 1,86
=6,83 - 1,86
=4,97 (b)
