hasil dari(2 1/4: 1/2-(0.35× 5/7)=

(2 ¼ : ½) - (0,35 × 5/7)

= (9/4 : ½) - (35/100 × 5/7)
= (9/4 × 2/1) - 175/700
= 18/4 - 7/28
= 126/28 - 7/28
= 119/28
= 4 7/28
= 4 ¼

Semoga membantu ;)

= (2 1/4 ÷ 1/2- {(0,35 = 35÷5/100÷5 = 7/20) × 5/7)
= (2 1/4 ÷ 1/2 - (7/20 × 5/7 = 35÷7/140÷7 = 5÷5/20÷5 = 1/4)
= (2 1/4 ÷ 1/2 - 1/4)
= {(2 1/4 = 9/4) ÷ 1/2 - 1/4)
= (9/4 × 2 - 1/4 = 18/4 - 1/4 = 17/4 = 4 1/4)
MAAF KALO SALAH
