the total distance of the road trip is 188.3 miles
Both Bob and Cheryl took turns and drove
Bob has driven 5/7th of the total distance
distance Bob has driven - 7 5 o f 188.3 mi l es
when the 'of' function is used we have to multiply
7 5 ∗ 188.3 = 7 5 ∗ 188.3 = 134.5
therefore distance Bob drove is 134.5 miles
Bob drove approximately 134.5 miles of the total 188.3 miles on their road trip. This is calculated by multiplying the total distance by 7 5 . Thus, Bob's driving distance can be found with a simple multiplication and division.

Penjelasan dengan langkah-langkah:Deret angka pada soal memiliki pola yang cukup sederhana, yaitu setiap suku memiliki selisih 2, atau setiap angka merupakan bilangan ganjil.Dengan begitu, deret angka pada soal bisa dilanjutkan menjadi 111, 113, 115, 117, 119 (dari 117 + 2), 121 (dari 119 +2), 123 (dari 121 + 2).Jadi, jawabannya adalah 119, 121, 123
