Question

Choose the decimal number that correctly represents the given diagram.

• A. 1.28
• B. 1.27
• C. 1.29
• D. 1.30

Answer 1

The correct option is A 1.28

In this figure, we have 100 small squares in one big square. There are 2 big squares. So each small square represents 1/100 = 0.01 unit.

We have 100 small squares filled with dots of the 1st big square. So these 100 small squares represent = 100 × 0.01 = 1. It will be the whole part of the decimal.

In the second big square, 28 small squares are filled with dots, so it will represent = 28 × 0.01 = 0.28. It will be the fractional part of the decimal.

Here, digit at ones place = 1, digit at tenths place = 2 and digit at hundredths place = 8.

So, the decimal number = 1.28
