Karina was given four days to fold some paper cranes. She folded 3/10 of them on the first day and 1/5 of the remainder on the second day. She folded 120 more on the third day than on the second day. She folded the remaining 279 paper cranes on the last day.

A) what fraction of the paper cranes was folded on the second day?

B) how many paper cranes did Karina fold altogether?

TIA!

Rahim, Sue and Tim had a total of 432 cards. After Rahim gave some of his cards to Sue, Sue had twice the number of cards she had at first. Then Sue gave some of her cards to Tim and Tim had twice the number of cards he had at first. In the end, the thee children had an equal number of cards. How many cards did Rahim have at first?

TIA!

B) 1st day --> 3/10 --> 15/50

2nd day --> 1/5 * 7/10 --> 7/50

3rd day --> 7/50 + 120

4th day --> 279

7/50 u+ 7/50 u+ 120 + 279 --> 7/10 u

21u --> 399

U = 19

50u--> 950

432/3 = 144 (Each child has 144 in the end).Daddy D wrote:Rahim, Sue and Tim had a total of 432 cards. After Rahim gave some of his cards to Sue, Sue had twice the number of cards she had at first.

144/2 = 72 (Tim has 72 at first, and Sue gave 72 to Tim)

72 + 144 = 216 (Sue has 216 before she gave some of her cards to Tim)

216/2 = 108 (Sue has 108 cards at first, and Rahim gave 108 cards to Sue)

144+108 = 252 (Rahim has 252 cards before he gave some of his cards to Sue)
