Answer 2

hye

=======================

aim :we have to Express 5/8 as a rational number with numerator 1) 15 2) -10

1)15

=>fraction is $\frac{5}{8}$

now we have to make it as

=>$\frac{5}{8} = \frac{15}{y}$

for finding y

=>5y = 8 *15

=>5y = 120

y = 24

∴ $\frac{5}{8} = \frac{15}{24}$

2)-10

=>fraction is 5/8

we have to make the numerator like this

=>$\frac{5}{8} = \frac{-10}{y}$

for finding y 

=>5y = -10 *8

=>5y = -80

=>y =-16

∴$\frac{5}{8} = \frac{-10}{-16}$
