Kylie has 2 times as many cookies as Abi. The total number of Kylie's and Abi's cookies is 6 times of Hilda's. Kylie and Abi have 55 cookies more than Hilda's. How many more cookies does Kylie have than Abi?
| Kylie |
Abi |
Hilda |
| 2x2 |
1x2 |
|
| 6x1 |
1x1 |
| 4 u |
2 u |
1 u |
The total number of cookies that Kylie and Abi have is repeated. Make the total number of cookies that Kylie and Abi have the same. LCM of 3 and 6 is 6.
Total number of cookies that Kylie and Abi have
= 4 u + 2 u
= 6 u
Number of more cookies that Kylie and Abi have than Hilda
= 6 u - 1 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
Number of more cookies that Kylie has than Abi
= 4 u - 2 u
= 2 u
= 2 x 11
= 22
Answer(s): 22
