The number of apricot shortbreads Cole baked was
57 of the total number of shortbreads. After baking another 27 apricot shortbreads, the number of apricot shortbreads became
45 of the total number of shortbreads. How many shortbreads did she bake at first?

Total shortbreads |
| Before |
5 u |
2 u |
7 u |

+ 27 |

| After |
4x2 =
8 u |
1x2 =
2 u |
5x2 =
10 u |
The number of other shortbreads remains unchanged. Make the number of other shortbreads the same. LCM of 2 and 1 is 2.
Number of more apricot shortbreads baked
= 8 u - 5 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of shortbreads that Cole baked at first
= 7 u
= 7 x 9
= 63
Answer(s): 63
