Ken had some cranberry tarts and apricot tarts.
310 of the number of cranberry tarts was equal to
18 of the number of apricot tarts. After Ken made 460 more cranberry tarts, the number of cranberry tarts was
73 of the number of apricot tarts. How many tarts did he have altogether in the end?
Make the numerators the same. LCM of 3 and 1 is 3.
310 of cranberry tarts =
1x38x3 of apricot tarts
310 of cranberry tarts =
324 of apricot tarts

The number of apricot tarts remains unchanged. Make the number of apricot tarts the same. LCM of 3 and 24 is 24.
Number of more cranberry tarts made
= 56 u - 10 u
= 46 u
46 u = 460
1 u = 460 ÷ 46 = 10
Number of tarts that Ken had in the end
= 56 u + 24 u
= 80 u
= 80 x 10
= 800
Answer(s): 800
