Gabby had five times the number of wooden blocks as George. Gabby used all her blocks to build 8 identical figurines. George used all his blocks to build 4 identical figurines. Gabby used 9 more blocks than George for each figurine. How many blocks did George have?

	Gabby	George
Number	8	4
Value	1 u + 9	1 u
Total value	8 u + 72	4 u

Number of wooden blocks that George used for each figurine = 1 u
Number of wooden blocks that Gabby used for each figurine = 1 u + 9

Number of wooden blocks that George had
= 4 x 1 u
= 4 u

Number of wooden blocks that Gabby had
= 8 x (1 u + 9)
= 8 u + 72

Gabby had five times the number of wooden blocks as George.

5 x 4 u = 8 u + 72
20 u = 8 u + 72
20 u - 8 u = 72
12 u = 72

1 u = 72 ÷ 12 = 6

Number of blocks that George had
= 4 u
= 4 x 6
= 24

Answer(s): 24
