To transfer a faction to a percent like this we can add a 0 to the 10 to make it 100 and a 0 to 9 to make it 90. In this case, the number is simple number rather than a decimal or something else more complicated that you might learn later. 90 of 100 is simplified to simply transferring 90 to 90% of 100 so the same goes for 9/10, 9 is 90% of 10.

9/10 would be 90%

To help you out a little more, it's really easy if the problem is stated like this.
1/10 = 10%
2/10 = 20%
3/10 = 30%
4/10 = 40%
5/10 = 50%
6/10 = 60%

and so on and so forth...

(2, 6)
x = 2
y = 6
y - x > -3
6 - 2 > -3
4 > -3
Therefore the answer is (2, 6)

We can say that because 3 times 9, which would equal 27, could be the same as 4*9, which would be 36. So Pat needs 36 pints of green paint. Down below is a tape diagram so you can see what it is.

A dartboard is divided into 20 sectors. Each sector is worth a point value from 1 to 20 and has shaded regions that double or

Nikitich [7]

The area of each sector is the amount of space on the sector

The area of the entire region is 6.89
The area of the double region is 0.75
The area of the triple region is 0.46

<h3>The area of the entire sector</h3>

The area of a sector is calculated as:

A = (1/2) × r^2θ

For the entire sector, we have:

θ = π/10

r = 6.625

So, we have:

A = (1/2) × 6.625^2 × π/10

Evaluate the product

A = 6.89

<h3>The area of the double region </h3>

For the double region, we have:

θ = π/10

r = 6.25

So, we have:

A = Complete sector - (1/2) × r^2θ

A = 6.89 - (1/2) × 6.25^2 × π/10

Evaluate the difference

A = 0.75

<h3>The area of the triple region </h3>

For the triple region, we have:

θ = π/10

R = 4.125

r = 3.75

So, we have:

A = (1/2) × R^2θ - (1/2) × r^2θ

A = (1/2) × 4.125^2 × π/10 - (1/2) × 3.75^2 × π/10

Evaluate the difference

A = 0.46

Hence, the area of the triple region is 0.46
