3 out of every 5 cards are number side down if 20 cards are number side up of how many cards are there in total

Question

Make an equation and show me the work

Answer 1

(2/5)x=20 , x the total of cards this will give x=50

So 20 cards up and 30 down

 

 

Answer 2

3 OUT OF EVERY 5 CARDS ARE NUMBER SIDE DOWN SO

3/5 OF THE CARDS ARE FACE DOWN

This means 2/5 are face up.

 

We have 20 cards face up and that is 2/5 of

the total cards 'c'

 

2/5(c) = 20

c = 20(5/2)

c = 10(5)

c = 50 cards total
