8/12×10/32+80%-2/3=mohon di bantu​

Ini ya kak 1) 8/12 x 10/32 + 80% – 2/3

= ⅔ x 5/16 + 4/5 – ⅔

= 5/24 + (12-10)/15

= 5/24 + 2/15

= 25/120 + 16/120

= 41/120

2) 5 1/5 – 2 1/4 x 0,5 + 45%

= 26/5 – 9/4 x ½ + 9/20

= 26/5 – 9/8 + 9/20

= 208/40 – 45/40 + 18/40

= (226-45)/40

= 181/40

= 4 ²¹/40
