To solve this problem you must apply the proccedure shown below. You have that:

 1+cot^2θ=csc^2θ    (You have that cos^2θ+sin^2θ=1)<span>
 1+(cos^2</span>θ/sin^2θ)=csc^2θ
 1+(1-sin^2θ/sin^2θ)csc^2θ
 sin^2θ+1-sin^2θ=csc^2θ
 1/sin^2=csc^2   (You have that 1/sin=csc)

jeka57 [31]

1.)

7 \frac{3}{9}  - 2 \frac{4}{9}  \\  =  \frac{66}{9}  -  \frac{22}{9}  \\  =  \frac{44}{9}  \\  = 4 \frac{8}{9}

2.)

11 \frac{3}{4}  - 5 \frac{1}{4}  \\  =  \frac{47}{4}  -  \frac{21}{4}  \\  =  \frac{26}{4}  \\  =  \frac{13}{2}  \\  = 6 \frac{1}{2}
