Answer is 36.
First use the negative exponent rule. When a number is put to the negative power it becomes a fraction
4/3^2

Now 3 to the second power is 9
4/1/9 (4 over 1/9)
Now multiply 4 x 9 (dividing by 1/9 is the same as multiplying by 9)

4 x 9= 36

We are given that Donna knit a total of 12 blankets.

She took 4 months in doing it.

To find the number of blankets in 1 month, take ratio of number of blankets to number of months.

$\frac{number \: of \: blnkets}{number \: of \: months} \\ \\ = \frac{12 \: blankets}{4 \: months} \\ \\ = \frac{3 \: blankets}{1 \: months}$

Thus, she knit 3 blankets in 1 months
