Anne has 24 more cards than Devi. Anne finds that 3/5 of Devi's cards are equal to 1/2 of her cards. How many cards does Anne have?

Answer 1

My answer is Anne have 144 cards..

Explanation:
Let x be the num of cards Devi have
x+24 be the num of cards Anne have

* since 3/5 of devis cards is equal to 1/2 of annes cards
So,
3/5x equals to 1/2( x+24)
(*my phone dont have an equal sign so let me use : as an equal sign)

3/5x : 1/2(x+24)
3/5x (2) : x+24
6/5x : x+24
6/5x - x : 24
6x-5x/5 : 24
x/5 : 24
x : 120

Check:

3/5(120) : 1/2(120+24)
72 : 1/2(144)
72 : 72
