Rael had some banana cookies and cheese cookies.
27 of the number of banana cookies was equal to
17 of the number of cheese cookies. After Rael made 336 more banana cookies, the number of banana cookies was
52 of the number of cheese cookies. How many cookies did he have altogether in the end?
Make the numerators the same. LCM of 2 and 1 is 2.
27 of banana cookies =
1x27x2 of cheese cookies
27 of banana cookies =
214 of cheese cookies

2x7 = 14 u |
49 u |
The number of cheese cookies remains unchanged. Make the number of cheese cookies the same. LCM of 2 and 14 is 14.
Number of more banana cookies made
= 35 u - 7 u
= 28 u
28 u = 336
1 u = 336 ÷ 28 = 12
Number of cookies that Rael had in the end
= 35 u + 14 u
= 49 u
= 49 x 12
= 588
Answer(s): 588
