10 u |
+ 20 + 34 |

- 4x2 =
- 8 u |
- 16 |
- 1 u |

|
After |
1x2 =
2 u |
+ 4 |
9 u |
10 u |
+ 54 |
205 |
45 x 20 = 16
LCM of 5 and 10 is 10.
Total number of items that was not broken
= 2 u + 4 + 9 u + 10 u + 54
= 21 u + 58
21 u + 58 = 205
21 u = 205 - 58
21 u = 147
1 u = 147 ÷ 21 = 7
Number of bowls that Risa had
= 10 u + 54
= 10 x 7 + 54
= 70 + 54
= 124
Answer(s): 124
