Juanita had 20 dollars to spend on 3 gifts. She spent 11 3/4
dollars on gift A and 6 1/2
dollars on gift B. How much money did she have left for gift C?

1 3/4 dollars.

Step-by-step explanation:

That is 20 - 11 3/4 - 6 1/2  Convert each number into a fraction with denominator = 4:

= 80/4  - 47/4 - 13/2

= 80/4 - 47/4 - 26/4

= 7/4

= 1 3/4.

$1 3/4 or $1.75 available to be spent on Gift C

Step-by-step explanation:

1) combine the costs of Gifts A and B:  11 3/4 + 6 1/2, or

   11 3/4 + 6 2/4  =  18 1/4

2) Subtract this result from $20:

   $20 - $18 1/4 = $1 3/4 or $1.75 available to be spent on Gift C.
