Take MCQ Maths Test1.
Kalai wants to cut identical squares as big as she can, from a piece of paper measuring 168 mm and by 196 mm. What is the length of the side of the biggest square? (To find HCF using repeated subtraction method)
2.
On a school trip, 56 girls and 98 boys went to Kanyakumari. They were divided into as many groups as possible so that there were equal numbers of girls and boys in each group. find the largest group possible? (To find the HCF using repeated division method)
3.
Do the given problems by repeated subtraction method and verify the result.
4.
Using repeated subtracting method find HCF of the following:
42 and 70
5.
In the given graph sheet draw and colour how the Fibonacci number pattern makes a spiral in the Golden Rectangle.
1.
Take m = 196 mm and n = 168 mm,
Here m > n.
196 - 168 = 28
168 - 28 = 140
140 - 28 = 112
112 - 28 = 84
84 - 28 = 56
56 - 28 = 28
28 - 28 = 0
The length of the side of the biggest square is 28 mm.
2.
14
3.
56 and 12
Take m = 56 and n = 12, Here m > n.
56 - 12 = 44
44 - 12 = 32
32 - 12 = 20
20 - 12 = 8
12 - B = 4
8 - 4 = 4
4 - 4 = A
The HCF of 56 and 12 is 4.
4.
Let number be m & n
m > n
We do m – n & the result of subtraction becomes new ‘m’.
if m becomes less than n, we do n – m and then assign the result as n.
We should do this till m = n. When m = n then ‘m’ is the HCF.
42 and 70 now m = 70, n = 42 70 – 42 = 28,
now m = 42, n = 28 42 – 28 = 14,
now m = 28, n = 14 28 – 14= 14,
now m = 14, n = 14
We stop here as m = n
∴ HCF of 42 & 70 is 14
