Jackie has two new puppies. one weighs 5 9/16 pounds and the other weighs 6 1/4 pounds. find the difference in their weights.

The difference in weights =  pounds

Step-by-step explanation:

"DIFFERENCE" means to subtract their weights. We will subtract lesser amount from the greater amount to get our answer.

Also, we need to first make these mixed numbers into improper fractions by using the rule below:

If a number is given in this form:

We can do the operation below to make it improper fraction:

The bigger number is . So we subtract the other from this after changing to improper fraction.

and

Now, we subtract via doing LCM and get our

The difference in weights =  pounds

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
