tentukan nilai dari 2 3 per 4 dibagi 1 per 4 dikali 5 per 12 dikurang 1 per 2

2 3/4 : 1/4 x 5/12 - 1/2

= 11/4 x 4/1 x 5/12 - 1/2
= 55/12 - 1/2
= 55/12 - 6/12
= 49/12 
= 4 1/12

kalo ada yang bingung bisa ditanyain yaa

2 3/4 ÷ 1/4 × 5/12 - 1/2
= 11/4 ×4/1 × 5/12 - 1/2
= [(11×4×5)/(4×1×12)] - 1/2
= 220/48 - 1/2
= 220/48 - 24/48
= 196/48
= 4 4/48
= 4 1/12
