Question

1. The greatest rational number among the following is
-4/5
- 23/50
-1
- 17/25​

Answer 1

Answer:

The correct answer is -1

Answer 2

given four numbers , find the largest rational number

Explanation:

1. numbers given are $-\frac{4}{5}\ \ \ -\frac{23}{50}\ \ \ -1\ \ \ -\frac{17}{25}$,  firstly lets determine which of the following is rational. to do so lets convert them to decimal point numbers,                                                                                                                         $-\frac{4}{5} = -0.8\\-\frac{23}{50} = -0.46\\-1\\-\frac{17}{25} = -0.68$  
2. Hence, all are rational numbers.
3. now since they are all negative numbers , we know that as we move forward towards left side of zero on the number line the values keep decreasing for example, $-5<-4$    
4. hence the given numbers are of order $-0.46>-0.68>-0.8>-1$  , greatest rational number among them is $-\frac{23}{50}$ (second option)
