Hey!
22) If y = [tex] \frac{1}{4} [/tex] then [tex] \frac{15}{y} = 15 \div \frac{1}{4} [/tex]
To divide fractions, you have to keep, change, flip.
[tex] Keep\ \frac{15}{1} \\ Change\ \div to \times \\ Flip \frac{1}{4} = \frac{4}{1} [/tex]
It becomes: [tex] \frac{15}{1} \times \frac{4}{1} = \frac{60}{1} \rightarrow 60 [/tex]
22. D)60
23) Circles measure 360°. 50° is left. Subtract 50 from 360 and make a fraction, using the difference as a numerator, and 360 as the denominator.
[tex] 360 - 60 = 300 [/tex]
The fraction becomes:
[tex] \frac{300 \div 30}{360 \div 30} = \frac{10 \div 2}{12 \div 2} = \frac{5}{6} [/tex]
23) A. [tex] \bf\frac{5}{6} [/tex]
Good luck and hope this helps! :)
