Maths Dlo

For each question, explain which person has more and how you know this.

Cyrus has 3/10 of 40 playing cards and Taimana has 1/3 of 36 cards.

Cyrus 12

Taimana 12

They both have the same amount of cards.  For Taimana I tried 18 but it went pass. Then I tried 11 but it was to small. So I tried 12 and I got it. For Cyrus I knew 4 x 10=40 so I knew 1/10 =4 and then I done 4+4+4=12
