9/10 of ailen races think invading earth is a bad idea

what percent of alien races think invading earth is bad?

90%

Step-by-step explanation:

you turn it into 90/100 which leaves you with 90%

90%

Step-by-step explanation:

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 9/10 as a percent, we need to find a fraction

equivalent to 9/10 that has a 100 in the denominator.

We can do this by setting up a proportion.

So we have 9/10 = n/10

Now, we can use cross-products to find the missing value.

So we have (9)(100) which is 900 is equal to (10)(n) or 10n.

So we have 900 = 10n.

Next, dividing both sides of the equation by 10, we have 90 = n.

So, 9/10 is equal to 90/100 or 90%.

Step-by-step explanation:

Radius = 7 inches

Angle of sector = 4pi/15

convert to degree = 4pi/15 × 180/pi = 48°

Area of sector = angle of sector/ angle of circle × pi × r²

= 48/360 × 22/7 ×7²

= 20 ⁸/15 inches²
