1. the average of seven numbers is 38.The sum of the first six number is 156.what is the seventh number?
Jawab:
x = seventh number
[tex]\frac{156+x}{7}[/tex] = 38
156+x = 38.7
156+x = 266
x = 266 - 156
x = 110
2. the average of seven numbers is 38.The sum of the first six number is 156.what is the seventh number?

3. the average of seven numbers is 38.The sum of the first six number is 156.what is the seventh number?
Jawab: 110
Penjelasan dengan langkah-langkah:
The average of seven numbers is 38,
(rata-rata dari ketujuh nomor adalah 38)
38 comes from The Sum of seven numbers : 7 (total amount numbers)
(38 didapat dari jumlah ketujuh nomor dibagi 7 (banyaknya nomor) )
so, The Sum of seven numbers = 38x7 = 266
(maka, total jumlah dari ketujuh nomor adalah = 38x7 = 266)
The sum of the first - six number is 156,
(total jumlah nomor dari 1 sampai 6 adalah 156) => tertera di soal
The Sum of seven numbers = 38x7 = 266,
(Total jumlah keseluruhan nomor adalah 266)
so, The seven number is 266-156 = 110
maka, angka ke 7 adalah 266-156 = 110

Translate: Aku sedang memikirkan sebuah angka. 80% dari angkanya adalah 56. Berapa angka aslinya?
80% = 56
100% = ???
Solusi:
80% ÷ 8
= 10% × 10
= 100% ← Angka asli
Ubah menjadi:
56 ÷ 8
= 7 × 10
= 70 ← Angka asli
Maka, angka yang kita pikirkan adalah 70.
