Solutions
To solve the problem we first have to convert the fraction into a decimal. To convert a fraction into a decimal you have to divide the <span>numerator</span> by the denominator.
7/8
= 7 ÷ 8
= 0.875
0.875 is bigger then 0.78 therefore 7/8 is greater.

Answer:
Step-by-step explanation:
Use the half angle formulas
sin(θ/2) = ±√((1 - cosθ)/2)
sin(θ/2) = ±√((1 - (3/5))/2)
sin(θ/2) = ±√((2/5)/2)
sin(θ/2) = ±√(1/5)
knowing θ is in the 4th quadrant, θ/2 will be in the second quadrant where sines are positive.
sin(θ/2) = +√(1/5) = √0.2
