Question

wieght of 20 tiles is 5kg what is the wieght of 7 tiles

Answer 1

Answer:

Please mark me as the brianliest I need it.

Step-by-step explanation:

20 tiles = 5kg

use unitary method

20/5 = 4

4 tiles = 1kg

7 tiles = 7/4 kg

Hence 7/4 kg is your answer.

Answer 2

we have the given data

weight of 20 tiles=5kg

weight of 7 tiles=?

weight of 1 tiles =x

20 tiles=5kg

1 tiles=x

so simplifying the value of x as cross multiplication

20=5

  1=x

$20x=5\\x=0.25$

this is the value of 1 tiles

we need to find weight of of 7 tiles

$=0.25 *7\\1.75kg$

so approximately weight of 7 tiles is 1.75kg
