A.15,2/3 - 7,3/4
B.6,1/3 - 8,2/3
C.5,1/6 - 13,2/3
D.7 - ... = 5,3/7
E.10,2/3 - ... = 5,1/5

2.Penjumlahan pecahan
A.2/3 + ... = 5/6
B.2,1/5 + ... =5,3/7

Answer 1

Verified answer

15 ⅔ - 7 ¾
= 47/3 - 31/4
= 95/12
=

6 ⅓ - 8 ⅔
= 19/3 - 26/3
= - 7/3

5 ⅙ - 13 ⅔
= 31/6 - 41/3
= - 17/2
= - 8 ½

7 - x = 5
x = 7 - 38/7
x = 11/7
x = 1

10 ⅔ - x = 5 ⅕
x = 32/3 - 26/5
x = 82/15
x = 5

Penjumlahan
⅔ + x = ⅚
x = ⅚ - ⅔
x = ⅙

2 ⅕ + x = 5 ³/₇
x = 38/7 - 11/5
x = 3
