Question

Y/4 - 3/5 enter answer as a reduced improper fraction

Answer 1

Answer:

$\frac{5y-12}{20}$

Step-by-step explanation:

the LCM of 4 and 5 is 20

We require the denominator of each fraction to be 20

Multiply numerator/denominator of first fraction by 5

Multiply numerator/denominator of second fraction by 4

$\frac{y(5)}{4(5)}$ - $\frac{3(4)}{5(4)}$

= $\frac{5y}{20}$ - $\frac{12}{20}$ ( subtract numerators, leaving common denominator )

= $\frac{5y-12}{20}$

Answer 2

The expression will be reduced to improper fraction as $\frac{5y-12}{20}$  where y should be greater than 6.4 .

What is improper fraction?

An improper fraction is defined as a fraction, whose numerator is greater than the denominator. Suppose, x/y is an improper fraction, such that x > y.

According to the question

The expression :

$\frac{y}{4} - \frac{3}{5}$

To convert it into improper fraction :

Step1: Take LCM of Denominators of both fractions

i.e

LCM of 4,5 = 20

Step2: Now divide denominator of fraction form LCM and multiply to numerator

i.e

$\frac{5y-12}{20}$

Now,

As we know In  improper fraction numerator > denominator

So,

$5y-12 > 20$

$5y > 32$

y > 6.4

Therefore ,

y should be greater than 6.4 to make it improper fraction .

Hence, The expression will be reduced to improper fraction as $\frac{5y-12}{20}$  where y should be greater than 6.4 .
