The price of a flight was increased by 3% to £650. What was the price before the increase?
liubo4ka [24]

Answer:

£ 631

Step-by-step explanation:

Hi this is a simple mathematics issue.

First, let's imagine what is 3%. '3 percents' means 3/100. If your family have 100 apples and you have 3 apples, that means you have 3% of your family apples.

Now, get back to this problem. We need to find the price before increase. Let's say the price was £ X. Now we will find the X number.

It's said that the price was increased by 3%. That means they took 3% of X and added that amount to X to have the new price : £ 650. That means we have this equation :

650 = X + 3%×X

Let's make it easier to look :

650 = X + 3/100 ×X

650 = X×( 1+ 3/100)

= X × 103/100

So we can see 650 is equaled to X multipled by 103/100.

To find the correct answer, simply divide 650 by 103/100.

*A hint: When you divide a number by a fraction, you can simply put the number multiplied by the "flipped" fraction .

Hope you learn with Joy and High Grades !!!

How do I simplify the n^-6*n^3 topic "Negative and Zero Exponents"
Alchen [17]
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3

n^-6 * n^3 = n^-3

If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.

n^-3 = n^-3 / 1 = 1/n^3

when the factor moves to the other side of the fraction, the side of the exponent changes.

the actual length of a rectangular platform used for assembeling robots is 6 feet. in amal's drawing, the platform measures 1.2
saw5 [17]

Answer:

Actual width = 5 feet.

Step-by-step explanation:

The ratio of 1.2 to 1  equals the ratio of length to width.

1.2 / 1  = 6 / w  where w is the actual width.

1.2w = 6

w = 6/1.2

w = 5.
