Okay, I got it- I took that quiz!!!! 0.57 is a rational number because it can be expressed as the quotient of two integers: 57 ÷ 1. It can be written as a fraction, 57/100

i don't know i am having the same problem on this question sorry

**English**

I am actually an ice skater! the first three sentences are all correct. 4 and 6 are correct.

**math**

20 + 13 + 6 = 39, which is the total number of people. 13 + 6 = 19, this tells us how many democrats and independents there are. So of the 39 people, 19/39 people are either democrats or independents

**math**

At a political rally there are 20 republicians, 13 democrates, 6 independents. If a person is chosen at random what is the probability that a) the person is either a democrate or and independent?
