It should be 6 as the first one is the outer square(biggest one) and there are 4 small squares inside it, which makes 5 squares. There is also one square inside the figure which is tilted. It looks like a rhombus but isn't a rhombus because a rhombus doesn't have 4 angles measuring 90 degrees.

Ans 20:

Reyansh Garg from Lotus Valley International School, Noida Extension
Class : Class 6
The correct answer is C because one is the outer square, then there are 4 squares inside it and one square is tilted so that will also count.

B AS we convert mixed to improper fraction so 4 1/2 = 2 x 4 1 /2 = 9/2 2 1/8 = 8 x 2 1 / 8 = 17/8 Then we find equivalent fractions 9/2 = 9 x 4 / 2 x 4 = 36 / 8 and 17 / 8 will remain same as we know. Now we do subtraction. 36 / 8 - 17 / 8 = 36 - 17 / 8 = 19 / 8 = 19 divided by 8= Quotient=2, Remainder=3 so 2 3/8
