Answer:

$\frac{7}{8} \div \frac{1}{2} = \frac{7}{4}$

Step-by-step explanation:

Here we are given four equations and we have to find the equation that gives the number of half inches that are in $\frac{7}{8}$ inches.

To find how many half inches i.e. $\frac{1}{2}$ inches are there in $\frac{7}{8}$ inches we have to divide $\frac{7}{8}$ by $\frac{1}{2}$ .

So, the equation that will give the result is $\frac{7}{8} \div \frac{1}{2} = \frac{7}{8} \times \frac{2}{1} = \frac{7}{4}$ (Answer)

David received $50 dollars for working at his father’s store. He spent $20 dollars at the movies, and $10 dollars buying comic b

statuscvo [17]

Total amount of money received by David for working at his father's store = $50
Amount of money spent by David at the movies = $20
Amount of money spent by David buying comics books = $10
Amount of money spent by David buying candy = $5
Then
Total amount spent by David = (20 + 10 + 5) dollars
       = 35 dollars
Amount of money saved by David = (50 - 35 ) dollars
   = 15 dollars
So
The ratio of the amount of money David
spent to the amount of money David saved = 35:15
      = 7:3
So the ratio of the amount of money David spent to the amount of money David saved is 7:3
