You would add up all the pencils to get yiur denominator, so the denominator would be 4+6=10. Since there is 4 red pencils, 4/10 of the pencils are red. To get an equivalent fraction, you can divide by 2. 4 divided by 2 is 2. 10 divided by 2 is 5. So one of your equivalent fractions would be 2/5. To get your second equivalent fraction you have to multiply because 5 is prime and cannot be divided by anything but itself and 1. 10X2=20 and 4X2=8. So your second equivalent fraction could be 8/20.

If this makes it easier here is the final equation.

4/10=8/20=2/5

Answer:

  • 84.7 units²
  • 118.125 in³

Step-by-step explanation:

The surface area of the triangular prism is the sum of its base areas and the lateral area. The total area of the two triangular bases is ...

  A = bh = 7(6.1) = 42.7 . . . square units

The lateral area is the product of the perimeter of the base and the length of the prism. The height given for the prism is consistent with it having triangular bases that are equilateral triangles. That is, the unmarked dimension is likely 7 units, so the perimeter is ...

  P = 7+7+7 = 21

and the lateral surface area is ...

  LA = PL = 21·2 = 42

Then the total surface area of the prism is ...

   total area = A + LA = 42.7 +42 = 84.7 . . . square units

__

The volume of a rectangular prism is given by ...

  V = Bh

where B is the area of the base, and h is the height. Your prism has a volume of ...

  V = (26.25 in²)(4.5 in) = 118.125 in³
