Question

Jawab nya pake cara ya.. Makasih ^^

Answer 1

1. 22 siswa = membaca
membaca = 110
1 siswa = 5
14 siswa = 14 × 5 = 7
70 = menyulam


2.madu = 240 = 25%
seluruhnya = 100/25 × 240 = 960


4.musik = 52 = 260 orang
1 = 5 orang
berita = 5 × 90 =450 orang
selisih = 450 - 260 = 190

#maaf kalo salah
yg 3 dan 5 ga keliatan

Answer 2

1.
Membaca
= 360 - (40+50+70+90)
= 360 - 250
= 110
110/360 X a = 22
11/36 a = 22
11a = 22 X 36
11a = 792
a = 792/11
a = 72
Jumlah sluruh siswa = 72
b/360 X 72 = 14
72b/360 = 14
72b = 14 X 360
72b = 5040
b = 5040/72
b = 70
(menyulam).

2.
25/100 X a = 240
5/20 a = 240
5a = 240 X 20
5a = 4800
a = 4800/5
a = 960

4.
Musik = 360 - (90+56+162)
= 360-308
= 52
52/360 X a = 260
13/90 a = 260
13a = 260 X 90
13a = 23.400
a = 23.400/13
a = 1.800
Jumlah keseluruhan = 1.800 orang

Berita = 90/360 X 1.800
= 1/4 X 1.800
= 450

Salisih = 450-260 = 190
