Maomao and Dongdong*** have 12 pictures. Maomao’s picture is twice as many as Dongdong’s. Maomao gives Rourou 3 pictures, which is the same number.

Maomao Dongdong=12

Maomao=2 Dongdong

3 Dongdong=12

Dongdong=4 (pieces)

Maomao=8 (pieces)

Maomao gives 3 pieces to Rourou, and she has 5 pieces left. At this time, she has the same number as Rourou

3 Rourou= 5

Rourou=2 (photos)

Just do the math after that
