+ 1x4 =
+ 4 u |
| After |

110 The number of stickers that Victoria gave to Diana is repeated. Make the number of stickers that Victoria gave to Diana the same. LCM of 1 and 4 is 4.
Number of stickers that Victoria had in the end = 44 u
44 u = 88
1 u = 88 ÷ 44 = 2
Number of stickers that Diana and Victoria had at first
= 5 u + 40 u
= 45 u
= 45 x 2
= 90
Answer(s): 90
