yang tau plis bantu jawab no 4-5 sama caranya jugaa

4)   12[tex] \frac{2}{5} [/tex] x [tex] \frac{40}{100} [/tex] : 1,6
      62/5 x 40/100 x 1/1,6
       3,1
5)  25% + (3[tex] \frac{1}{3} [/tex] : 1,6)
     1/4 + ( [tex] \frac{10}{3} [/tex] : 1,6)
     0,25 + 2,08
     3,33

1.  5 × 12 = 60 + 2 = 62/5
     40% = 40/100 = 8/20 = 2/5
     1,6 = 16/10 = 8/5
62/5 × 2/5 = 124/25
124/25 ÷ 8/5 = 124/25 × 5/8 = 620/200 = 62/20 = 31/10
2. 25% = 25/100 = 5/20 = 1/4
    3 × 3 + 1 = 10/3
    1,6 = 16/10 = 8/5
10/3 ÷ 8/5 = 10/3 × 5/8 = 50/24 = 25/12
25/12 + 1/4 = 26/16 = 13/8
semoga jawabanku bisa membantu
