tolong buat PTS senin?!!!?

(5/6 - ¼) ÷ ( ⅔ + ½)
= ( 10/12 - 3/12) ÷ ( 8/12 + 6/12)
= 7/12 ÷ 14/12
= (7÷14) / (12÷12)
= (7/14) / 1
= 7/14

( 5/6 - 1/4 ) ÷ ( 2/3 + 1/2 )

= ( 10/12 - 3/12 ) ÷ ( 4/6 + 3/6) = 7/12 ÷ 7/6

= 7/12 × 6/7 = 42/84

= 7/14 ( karena masing masing dibagi 6 )

semoga jawabannya betul dan maaf kalo salah ^_^
