Answer:

There is 7/15 left in the bag

Step-by-step explanation:

So, you need to find a common denominator between 3 and 5 which is 15

multiply the numerator and the denominator by 3 in 1/5. Then, multiply the numerator and the denominator by 5 in 1/3.

1/3*5=5/15

1/5*3=3/15

Add them together.

5/15+3/15=8/15

Lastly, subtract 15/15 by 8/15

15/15-8/15=7/15

lorasvet [3.4K]
<span>1. To solve this problem you must apply the formula for calcúlate the area of a trapezoid, which is shown below: 
 
 A=(B+b)h/2
 
 A is the area of the trapezoid (A=24).
 B is the larger base </span>of the trapezoid <span>(B=5).
 b is the smaller base </span>of the trapezoid<span> (b=5).
 h is the height </span><span>of the trapezoid.
 
 2. You must clear "h" from the formula:
</span><span> 
 A=(B+b)h/2
</span> 2A=<span>(B+b)h
</span> h=2A/<span>(B+b)
</span><span> 

  3. When you susbtitute the values into </span> h=2A/(B+b), you obtain:
 
 h=2A/<span>(B+b)
</span><span> h=2(24)/(5+3)
 h=48/8
