Question

Tolong bantu ya !! perbandingan ..

Answer 1

Perbandingan senilai, kalikan silang
a). p= 30/48 × 8 = 5

b). p= 84/60 × 5 = 7

c).
p+1= 120/96 × 4
p+1= 5
p=5-1
p=4

d).
6p-3 = 3/5 × 75
6p-3= 45
6p=45-3
p=42/6=7

e).
15(p+2)=32p
15p+30=32p
32p-15p=30
17p=30
p=30/17

f).
6(3p)=4(12-p)
18p=48-4p
18p+4p=48
22p=48
p=48/22
p=24/11

g) p = 2/9 × 3 = ⅔

h) p = 8/(¾) × 9= 8× 4/3 × 9 = 96
