Question

BANTUIN PLEASE...
1 . 3/4x - 1/2 = 18 1/4 (18nya gabung sama 1/4. bacanya delapanbellas satu per empat)
2. n/2 = 3 2/5 = 17/2 + 2/5 (3 sama 2/5 gabung ya)

Answer 1

1) 3/4x - 1/2 = 73/4
    3/4x = 73/4 + 1/2
    3/4x = 73/4 + 2/4
    3/4x = 75/4
    x = 75/4 / 3/4
    x = 75/4 * 4/3
    x = 75/3
    x = 25

yang nomer 2 gini kali soalnya >> n/2 - 3 2/5 = 17/2 + 2/5 ?
2) n/2 - 17/5 = 85/10 + 4/10
    n/2 = 89/10 + 17/5
    n/2 = 89/10 + 34/10
    n/2 = 123/10
    n = 12,3 * 2
    n = 24,6
