Jawab donk kak,,besok ditumpuk

1]7.5 – 3/5 -1 1/5 = (pecahan)

Jawaban:

$1)7.5 - frac{3}{5} - 1 frac{1}{5} \ = frac{75}{10} - frac{3}{5} - frac{6}{5} \ = frac{75 - 6 - 12}{10} \ = frac{57}{10} \ = 5 frac{7}{10}$

$2)1 frac{1}{2} + 2 frac{3}{4} + 3.5 \ = frac{3}{2} + frac{11}{4} + frac{35}{10} \ = frac{30 + 55 + 70}{20} \ = frac{155}{20} = frac{31}{10} = 3 frac{1}{10}$

$3)1 frac{3}{8} + frac{1}{5} + 2 frac{1}{2} \ = frac{11}{8} + frac{1}{5} + frac{5}{2} \ = frac{55 + 8 + 100}{40} \ = frac{163}{40} = 4 frac{3}{40}$

#sgitu ajaa dehh kelamaan kl smua

#maaf

#caranya sama smua kok

kalo yg dibagi dijadiin kali terus dibalik baru dihitung
