Question

In the expression shown, w represents a rational number.

Answer 1

Answer: b:23/21

Step-by-step explanation:

To get the value of w that makes the expression equal a number greater than 15.3, we multiply 15.3 by the values given in the options. This will be:

a: 13/14

= 15.3 × (13/14)

= 14.2

b:23/21

= 15.3 × (23/21)

= 16.8

c:42/42

= 15.3 × (42/42)

= 15.3

d:100/101

= 15.3 × (100/101)

= 15.2

From the illustrations given from a-d, we can see that only option b with w given as 23/21 makes the expression greater than 15.3
