The answer is 19 $\frac{1}{4}$

First you must set up the equation

$-2\frac{3}{4}$ ÷ $-\frac{1}{7}$

First, you must make the mixed number a improper fraction

$-\frac{11}{4}$ ÷ $-\frac{1}{7}$

Then you must divide

Karen has one nickel one dime one quarter one half dollar and one silver dollar. If she lost one coin she has exactly seven time

spayn [35]

Answer:

If she started with a nickel, a dime, a quarter, a half-dollar, and a dollar, she started with $1.90, which is to say 190 cents.

If she takes away one of the coins she either has 185, 180, 165, 140, or 90 cents remaining. Only one of those numbers is evenly divisible by 7.
