Matthias and hui min had 48 Pokemon cards. Matthias gave 1/2 of his pokemon cards to hui min. in return, hui min gave 2/5 of her total pokemon cards to Matthias. if they have the same number of pokemon cards now, how many pokemon cards did Matthias have at first?
thanks -
in the end
m=24
h=24
work backwards, h gave 2/5…so left with 3/5 = 24
1/5 = 8
5/5 = 40
h=40
m=8, m gave 1/2 left 8
so m have 16 at first -

Hi, I need some help for the following questions:

Ben had 1/3 of the marbles. Charles had 210 marbles.
How many marbles did they have altogether?
(2) Caline had 120 beads at first. She gave 35 beads to Danny and a
number of Beads to Elle. Caline then had 1/3 of her beads left.
How many beads did Caline give to Elle?
Thank you in advance. -

Ben had 1/3 of the marbles. Charles had 210 marbles.
How many marbles did they have altogether?
Ali had 1/3
Ben had 1/3
So Charlier have the remainder which is also 1/3.
1/3 = 210
In total they have 210 x 3 = 630 -
