Step by step solution because that calculating 28 is 40 percent of what number

We currently have our an initial value 28 and the second value 40. Let"s assume the unknown value is Y i m sorry answer us will discover out.

You are watching: Twenty-eight is 40% of

As we have actually all the forced values us need, now we have the right to put lock in a basic mathematical formula together below:

STEP 128 = 40% × Y

STEP 228 = 40/100× Y

Multiplying both political parties by 100 and dividing both sides of the equation through 40 we will arrive at:

STEP 3Y = 28 × 100/40

STEP 4Y = 28 × 100 ÷ 40

STEP 5Y = 70

Finally, we have found the value of Y i m sorry is 70 and also that is our answer.

You can easily calculate 28 is 40 percent that what number through using any regular calculator, simply enter 28 × 100 ÷ 40 and you will get your answer which is 70

Sample questions, answers, and how to

Question: her friend has a bag the marbles, and he tells you the 40 percent of the marbles are red. If there are 28 red marbles. How countless marbles walk he have altogether?

Answer: 70 marbles.

How To: In this problem, we recognize that the Percent is 40, and also we are additionally told the the part of the marbles is red, therefore we recognize that the component is 28.

So, that means that it should be the total that"s missing. Below is the means to number out what the total is:

Part/Total = Percent/100

By making use of a straightforward algebra we have the right to re-arrange our Percent equation choose this:

Part × 100/Percent = Total

If us take the "Part" and also multiply the by 100, and then we division that by the "Percent", we will get the "Total".

Let"s try it the end on our problem around the marbles, that"s very straightforward and it"s simply two steps! We know that the "Part" (red marbles) is 28.

So action one is to just multiply that component by 100.

28 × 100 = 2800

In step two, us take that 2800 and divide it by the "Percent", i beg your pardon we space told is 40.

So, 2800 separated by 40 = 70

And that method that the total number of marbles is 70.

Question: A high college marching band has actually 28 flute players, If 40 percent of the tape members pat the flute, then how many members space in the band?

Answer: There space 70 members in the band.

How To: The smaller "Part" in this difficulty is 28 since there are 28 flute players and we space told the they make up 40 percent of the band, therefore the "Percent" is 40.

Again, it"s the "Total" that"s absent here, and also to discover it, we simply need to follow our 2 action procedure together the vault problem.

For action one, us multiply the "Part" through 100.

28 × 100 = 2800

For step two, we division that 2800 through the "Percent", i beg your pardon is 40.

2800 separated by 40 equals 70

That way that the total variety of band members is 70.

Another step by action method

Let"s i think the unknown worth is Y

First writing it as: 100% / Y = 40% / 28

Drop the portion marks to simplify your calculations: 100 / Y = 40 / 28

Multiply both sides by Y to relocate Y on the appropriate side the the equation: 100 = ( 40 / 28 ) Y
