Question

The number of glasses of water Ted drinks in a given number of hours is tabulated in the table given below. What will the missing value in the table be?

Number of hours	$1$	$2$	$4$
Number of glasses of water	$2$	$4$	?

• A. $4$
• B. $8$
• C. $16$
• D. $6$

Answer 1

The correct option is B $8$

To find the missing value, let’s make a ratio table.
The equivalent ratios are $1:2,2:4,$ and $4:8.$
Observing the ratio table, we can see that Ted will drink $8$ glasses of water in $4h.$
So, the missing value will be $8.$
