hitunglah hasil penjumlahan dan pengurangan bentuk pexahn berikut a.1/5 + 3/7 b.4 1/3 + 3/4 c3/4-2/5 d.1/2 -1/3

A.
[tex] \frac{1}{5} + \frac{3}{7} = \frac{7}{35} + \frac{15}{35} = \frac{22}{35} [/tex]

B.
[tex]4 \frac{1}{3} + \frac{3}{4} = 4 \frac{4}{12} + \frac{9}{12} = 4 \frac{13}{12} = 5 \frac{1}{12} [/tex]

C.
[tex] \frac{3}{4} - \frac{2}{5} = \frac{15}{20} - \frac{8}{20} = \frac{7}{20} [/tex]

D.
[tex] \frac{1}{2} - \frac{1}{3} = \frac{3}{6} - \frac{2}{6} = \frac{1}{6} [/tex]

a. 1/5 +3/7 = 7/35 + 15/35 = 22/35 = 0.62
b. 4 1/3 + 3/4 = 13/3 +3/4 = 52/12 + 9/12 = 61/12 = 5.08
c. 3/4- 2/5 = 15/20 - 8/20 = 7/20 = 0.35
d. 1/2 - 1/3 = 3/6 - 2/6 = 1/6 = 0.16
