Answer :
If Mo is thinking a number and eleven more than one third of the number is -1, then the Mo's number is -36
Mo is thinking a number
Consider the number as x
Then one third of the number = (1/3) × x
= x/3
Eleven more than one third of the number = (x/3) +11
Eleven more than one third of the number is -1
Form an equation using the given details
(x/3) + 11 = -1
Subtract 12 on both side of the equation
x/3 = -1-11
x/3 = -12
x = -12 × 3
x = -36
Hence, if Mo is thinking a number and eleven more than one third of the number is -1, then the Mo's number is -36
