There are 25 Note books and 20 pens on a table. find the ratio of i) Number of pens to number of note books

ii) number of Note books to the total number of objects on the table

by objects I mean Note books and pens​

i] 4:5

ii] 5:9

Step-by-step explanation:

i] no. of pens/ no. of notebooks

20/25

4/5

= 4:5

ii] no. of notebooks/ total no. of pens and notebooks

25/ 20+25

25/ 45

5/ 9

5:9

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
