It is given that each sweet packet must have same number of strawberry-flavored, orange-flavored and pineapple-flavored sweets.
We need to find the common factor of 25,35 and 36 that can evenly divide all the numbers.
25=5×535=5×736=2×2×3×3
Hence, there is no common factor to all the three numbers, except 1.
These are relatively prime numbers.
∴ Only one sweet packet can be made out of 25 strawberry-flavored, 35 orange-flavored and 36 pineapple-flavored sweets.
