A three-column table is given.

Question

Part A C D
Part 14 28 63
Whole B 40 90

What is the value of B in the table?
20
25
28
30

Answer 1

To find the value of B, we need to compare the relationship between Part and Whole in columns A and C.

In column A, Part is 14 and Whole is B. In column C, Part is 28 and Whole is 40.

From this comparison, we can see that when the Part doubles from 14 to 28, the Whole also doubles from B to 40.

Therefore, the value of B must also be doubled from 14 to 28.

So, the value of B in the table is 28.
