Write each rational number as a ratio of two integers

1. -6.7
2. 0.7
3. 3 8/9
4. -4 2/3
5. -0.23
6. 7.1
7. 1

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

it’s supposed to be -4+45=41
