Question

Express 7 by 4 as a rational number with denominator - 16 and 24

Answer 1

hye

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



aim :we have to Express 7/4  as a rational number with numerator 1) -16 2) 24

1)- 16

=>fraction is  7/4

now we have to make it as

=>$\frac{7}{4} = \frac{x}{-16}$

for finding y

=>4x = -16*7

=>4x = -112

=>x = -112/4 = -28

=>x = -28

∴ $\frac{7}{4} = \frac{-28}{-16}$

2)24

=>fraction is 7/4

we have to make the denominator like this

=>$\frac{7}{4} = \frac{x}{24}$

for finding x 

=> 4x = 24*7

=>4x = 168

=>x = 168/4

=>x =  42


∴ $\frac{7}{4} = \frac{42}{24}$

hope it helps u .........

Answer 2

Answer:

Step-by-step explanation:

1)- 16

=>fraction is  7/4

now we have to make it as

=>

for finding y

=>4x = -16*7

=>4x = -112

=>x = -112/4 = -28

=>x = -28

∴ 

2)24

=>fraction is 7/4

we have to make the denominator like this

=>

for finding x 

=> 4x = 24*7

=>4x = 168

=>x = 168/4

=>x =  42

7/4=42/24
