that would be 2 over 9
It has been doubled.
Find the least common denominator of 10 and 15, which is 30. If 15 is doubled to 30, the 8 over it must be doubled to 16. If 10 is tripled to 30, the 9 over it must be tripled to 27. 27 over 30 minus 16 over 30 is 11 over 30.

Two dollars.
1/4 x 2 = 1/2 0.25 x 2 = 0.5
1/9 + 1/3 = 1/9 + 3/9 = 4/9
doubled 9 is 18 bc 9 times 2 is 18 and doubled means times it by 2
1 -------- 9-7 -------- 9
1/3+ 1/9= 4/9.
16 over 9 or 1 and 7 over 9.
One doubled once is 1*2. One doubled twice is 1*22. One doubled three time is 1*23=8.... One doubled 64 times is 1*264=264, or approximately 1.84*1019, or 18.4 quintillion.
