Lee, Shawn, and Jade share a box of 754 beads. The ratio of Lee's share of beads to Shawn's share of beads is 4 : 3. The ratio of Shawn's share of beads to Jade's share of beads is 9 : 5. How many beads does Lee have?

I could be wrong but ... I will try to answer

you first find the common factor

4:3 and 9:5

then

4 times 3 is 12

5 times 3 is 15

the ratio is now:

12:9:15

add the numbers up and that would be 36

divide 754 by 36

which is about 20.94444 ...

multiply 20.94 by 12, 9, and 15

12 would be 251.28

9 would be 188.46

15 would be 314.1

add them together and they would be about 753.84
