Sagot :
Answer:
y = 18
Step-by-step explanation:
i) reduce the fraction with 4
[tex] \frac{28}{36} = \frac{14}{y} [/tex]
[tex] \frac{28 \div 4}{36 \div 4} = \frac{14}{y} [/tex]
[tex] \frac{7}{9} = \frac{14}{y} [/tex]
ii) simplify the equation with cross multiplication
[tex] \frac{7}{9} = \frac{14}{y} [/tex]
[tex]7y = 14 \times 9[/tex]
[tex]7y = 126[/tex]
iii) divide both sides of the equation by 7
[tex] \frac{7y}{7} = \frac{126}{7} [/tex]
[tex]y = 18[/tex]
