There are 20 books in 4 boxes. How many books are there in 1 box?

There are 5 books in 1 box

Step-by-step explanation:

It is quite easy to solve. You have to use division to figure out how many books go in each box. Our division equation will be: 20 ÷ 4 = ?

We will divide 20 by 4 and our answer is 5.

We can double-check our answer by doing multiplication. 5 x 4 = 20, leading us back to the original 20 books that are in boxes.

So, there are 5 books in each box.

2nd one in the first row is correct

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
