1.Jessica lost some of her money. She found 3/6 of it. What fraction of her money is still missing ? 2.If there are 16 ounces in a pound and a baby weighs 10 pounds, how many ounces does he weigh?

Jessica lost 3/6 of her money, or 1/2 of it (divide 3 from top and bottom).
1 - 1/2 = 1/2. 
1/2 of Jessica's money is still missing.

There are 16 oz in 1 pound
The baby weighs 10 pounds

multiply the oz with the amount of pounds
16 x 10 = 160
the baby weighs 160 oz

hope this helps
