Tolong di Bantu ya teman-teman A. 4/5 x 3/5 + 2/7 B. 2 : 6/7 + 3 1/4 C 2/7 - 1/9 : 29

A. 4/5 x 3/5 = 12/5 + 2/7
= 84/35 + 10/35 = 94/35
= 2 25/35
= 2 5/7

B. 2/1 : 6/7
= 2/1 x 7/6 = 7/3
7/3 + 13/4
= 28/12 + 39/12 = 67/12
= 5 7/12

C. 1/9 : 2/9
= 1/9 x 9/2 = 1/2
2/7 - 1/2
= 4/14 - 7/14 = -3/14

a. 4/5×3/5+2/7
=12/5 + 2/7
=84/35 + 10/35
=94/35

b.2:6/7+3 ¼
=2×7/6 + 13/4
=14/6 + 13/4
=28/12 + 39/12
=67/12
=5 7/12

c.2/7 - 1/9 : 29
=2/7-9/1×29
=2/7-261/1
=2/7-1827/7
= -1825/7
= -260 5/7
