For every 10 sweets that Zoe has, Gem has 2 more sweets than her. They have 66 sweets altogether. How many sweets does Gem have?
Number of sweets that Gem has in 1 set
= 10 + 2
= 12
Total number of sweets in 1 set
= 12 + 10
= 22
Number of sets
= 66 ÷ 22
= 3
Number of sweets that Gem has
= 3 x 12
= 36
Answer(s): 36
