Answer:

Number 11: She has to add 5/36 of a cup

Number 12: The present costs $22,2

Number 13: 56,7 pounds is the weight of the package.

Number 14: You started with 40 muffins

Step-by-step explanation:

Number 11: 1/4 = 9/36 and 1/9 = 4/36

3*1/4 - 3*1/9 = 3*9/36 - 3*4/36 = 5/36

Number 12: 13,32/x= 3/5 ( or 0,6)

x = 13,32/0,6 = 22,2

Number 13: x * 5/7 = 40,5

x = 40,5/ (5/7) or 40,5 * 7/5 = 283,5/5 = 56,7

Number 14: 12/x = 3/10 (or 0,30)

x= 12/0,30 = 40
