Viki and Danwen shared the driving on a 180-mile road trip. Viki drove 60 miles and Danwen drove 120 miles. which shows the ratio of Danwens miles to all the miles they drove

1:2

Step-by-step explanation:

We shall just put the figures in ratio to compare and make the perfect ratio

Viki : Danwen

60 : 120

In perfect ratio form, we need the ratios to be keep dividing with same number to bring them down to lowest possible whole number

Here, we'll divide both by 10, and get this:

6 : 12

We can still divide both with 6 and get:

1:2

We can divide it further so it's our answer.

Which shows Danwen drove double than Viki.

i think is g(1)=-1.

hope that i can
