a. 11/15 + 12/30 = n
b. 15/17 + 1/34 = n
c. 3 1/6 + 5 2/7 = m
d. 3 3/4 + 7 5/12 = m
e. 6 3/9 + 7 5/12 = m
f. 7 1/5 + 8 7/10 = m
tolong dong kk…caranya kasih tahu?
Carilah nilai m dan n pd pnjumlahan ini !
a. 11/15 + 12/30
= 22/30 + 12/30
= 34/30
= 1 4/30
= 1 2/15
b. 15/17 + 1/34
= 30/34 + 1/34
= 31/34
c. 3 1/6 + 5 2/7
= 19/6 + 37/7
= 133/42 + 222/42
= 355/42
= 8 19/42
d. 3 3/4 + 7 5/12
= 15/4 + 89/12
= 45/12 + 89/12
= 129/12
= 10 9/12
= 10 3/4
e. 6 3/9 + 7 5/12
= 57/9 + 89/12
= 228/36 + 267/36
= 495/36
= 13 27/36
= 13 3/4
f. 7 1/5 + 8 7/10
= 36/5 + 87/10
= 72/10 + 87/10
= 159/10
= 15 9/10
