Gabby made 76 puffs and croissants. After she gave 0.3 of the puffs and 0.75 of the croissants to her friends, she was left with an equal number of puffs and croissants. How many croissants had she left?

Puffs |
Croissants |
Before
|
10x1 =
10 u |
4x7 =
28 u |
Change
|
- 3x1 =
- 3 u |
- 3x7 =
- 21 u |
After
|
7x1 =
7 u |
1x7 =
7 u |
Comparing puffs and
croissants in the end |
1x7 =
7 u |
1x7 =
7 u |
0.3 =
310 0.75 =
75100 =
34 The number of puffs and croissants is the same in the end. Make the number of puffs and croissants in the end the same. LCM of 7 and 1 and 1 is 7.
Total number of puffs and croissants at first
= 10 u + 28 u
= 38 u
38 u = 76
1 u = 76 ÷ 38 = 2
Number of croissants that Gabby had left
= 7 u
= 7 x 2
= 14
Answer(s): 14
