5/8 of 4 use the following image to multiply ​

2 1/2 or 2.5

Step-by-step explanation:

As you can see in the image, there are 4 whole rectangle's, each divided into two halves. That give's us 8 total parts to work with. Knowing that we need to find 5/8 of 4, simply fill in 5 of those parts. As two parts equal one whole, and one part equals one half, we can determine that 5/8 of 4 converts to 2 1/2, or 2.5.

Equation:   of=multiplication

5/8*4=2 1/2

5*4=2020/8

20/8 as a mixed number is 2 4/8, which simplifies to 2 1/2.  

i would need to see the dot plot : )

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
