m = 3/8 : 3/4
m = 3/8 x 4/3
m = 12/24
m = 1/2

n = 2 1/3 - 1 1/7
n = 7/3 - 8/7
n = 49/21 -  24/21
n = 25/21

m + n
= 1/2 + 25/21
= 21/42 + 50/42
= 71/42
= [tex]1 \frac{29}{42} [/tex]  (A)

2,4 x 1/4
= 0,6 ton

2,4 - 0,6
= 1,8 ton

3/4 ton = 0,75 ton

Maka, ikan yang dijual ditempat pelelangan
= 1,8 - 0,75
= 1,05 ton (A)

Semoga Membantu!!!
