20 3/4 - 5 1/2 tolong kasih tau caranya ya

Pembahasan :
[tex]20 \frac{3}{4} - 5 \frac{1}{2} \\ = \frac{83}{4} - \frac{11}{2} \\ = \frac{83 - 22}{4} = \frac{61}{4} = 15 \frac{1}{4} [/tex]

Good Luck ^^

Ans :

20 ¾ - 5½


20¾ = ( 20 x 4 ) + 3 = 80 + 3 = 83/4
5½ = ( 2 x 5 ) + 1 = 10 + 1 = 11/2

Maka :

20¾ - 5½
= 83/4 - 11/2
= 83/4 - 22/4
= 61/4
= 15 1/4


I HOPE THIS HELPS
