Question

pls with explanation!!

Answer 1

Answer:

5 can be used in place of x. First we will take out the lcm of 5 which is 35, the numbers become 3/5*7/7 = 21/35, x/7*5/5 = 5x/35 and 4/5*7/7 = 28/32. We get 21/35, 5x/35 and 28/35. Now the only number which remains greater than 21/35 and lesser than 28/35 when multplied by 5 is 5, therefore x is 5.

Answer 2

Step-by-step explanation:

multiply in 3/5 by 7/7 = 21 /35.

multiply in 4/5 by 7/7 = 28 /35.

Now denominator is same,

Take a one number like 25/35 which lie between 21/35 and 28/35.

In 25/35 ,multiply by 5/5 = 5/7

the numerator of 5/7 is 5.

Hope it's help.
