If Mike is 6 years old and twice as old as his brother, then his brother is 3 years old. When Mike is one and a half times his brother's age (1.5 * 3 = 4.5), he will be 4.5 years older than his brother. Therefore, Mike will be 6 + 4.5 = 10.5 years old when he is one and a half times his brother's age.
9 years
if you mean 8 times a half, then you work it out like this: 2 times a half is: 1 4 times a half is: 2 8 times a half is: 3
I am not sure if this is the correct process but as I understand it, this is my solution: Since Jane is 6 years old and she is twice as old as her brother. Which means Jane's brother is 3 years old. brother = x Jane = 2x 2x = 6 x= 3 Now, we need to solve for the year/s needed for Jane to be one and half times older than his brother: years = x Jane = 6 brother = 3 1.5 ( 3 + x) = 6 + x 4.5 + 1.5x = 6+ x 1.5 x - x = 6 - 4.5 .5x = 1.5 x = 3 Therefore, Jane is 9 (6+3) and her brother is 6 ( 3+3). Is this correct??
The answer is 2.5.
