An Internet site sells 120 types of cell phones. The ratio of the number of smartphones to the number of feature phones is 3:5. How many of the 120 types of cell phones are smartphones?

Answer 1

3:5 = 3/5

Smartphones = (3×120)/8 = 35

Thus, 35 are smartphones.

Answer 2

45 Smartphones are sold by the internet site.

Step-by-step explanation:

An internet site sells 120 types of cell phones.

Ratio of the number of smartphones to the number of feature phones = 3 : 5

Sum of ratio = 3 + 5

                    = 8

Number of smartphones sold =  $\frac{120}{8}\times 3$

                                                 =  15 × 3

                                                 = 45

Number of feature phone sold = $\frac{120}{8}\times 5$

                                                   = 15 × 5

                                                   = 75

45 Smartphones are sold by the internet site.
