Question

hasil dari 3 1per4 ditambah 3per8 dikurangi 1 2per3​

Answer 1

3 ¼ + ⅜ - 1 ⅔ = . . .?

(3 × 4 + 1)/4 + ⅜ - (1 × 3 + 2)/3

13/4 + ⅜ - 5/3

= ../24 + ../24 - ../24

= (24 ÷ 4 × 13)/24 + (24 ÷ 8 × 3)/24 - (24 ÷ 3 × 5)/24

= 78/24 + 9/24 - 40/24

= 87/24 - 40/24

= 47/20

= 2 7/20

Answer 2

3 1/4 + 3/8 - 1 2/3

= 13/4 + 3/8 - 5/3

= (78 + 9 - 40)/3

= (78 + (-31)/3

= (78 - 31)/3

= 47/20

= 2 7/20
