Fractions is equipment to 3/8

I think you meant to say "equivalent" instead of "equipment"

To find equivalent fractions to 3/8, you would multiply top and bottom by the same number.

If we multiply the top and bottom by 5 for instance, then

3*5 = 15

8*5 = 40

So 3/8 is equivalent to 15/40

Another example: multiply top and bottom by 9

3*9 = 27

8*9 = 72

This means 3/8 is equivalent to 27/72

Now let's say you were asked if 15/40 was equivalent to 3/8

To check this, you would assume they are equal, then cross multiply like so

15/40 = 3/8

15*8 = 40*3 ... cross multiply

120 = 120

Since we end up with the same thing on both sides, we have confirmed that 15/40 = 3/8 is a true equation.

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.
