Q.1) No of students in class- 30
No  of students liking football- 6
No of students liking cricket- 12

=30-6+12
=30- 18
= 12 liking tennis

Ratio of cricket to tennis is 6:12=1:2 in it's simplest form

No of students: No of students liking cricket
12:30=2:5 in it's simplest form

Q.2) Breadth-10, 20, 40
Length- 25, 50, 100

2nd column
= 50÷5x2
=10x2
= 20= answer

3rd column
= 40÷2x5
= 20x5
=100= answer

Q.3) 1) 1 hour = 60 minutes
48:60
HCF= 12
48÷12=4
60÷12= 5
4:5

2) 1 meter = 100 cm x 2= 200cm
200:35
HCF=5
200÷5= 40
35÷5= 7
7:40

Q.4) LCM of 8 and 7= 56
4/7= 32/56
5/8= 35/56

35/56 > 32/56
5/8 > 4/7
5:8 > 4:7

Therefore, 5:8 is bigger than 4:7

Q.5) Total students in class- 45
Ratio of boys to girls- 5:4

5+4=9=total parts
45÷9=5

girls=
=4x5
=20 girls

boys=
=5x5
=25

Therefore, there are 25 boys and 20 girls

Q3
1] 48:60 :: 4:5
2] 200:35 :: 40:7

Q4
LCM of 7 and 8
56

4:7 = 4⁄7
5:8 = 5⁄8

4x8= 32
7x8= 56

5x7= 35
8x7= 56

35⁄56 = 35:56
32⁄56 = 32:56
35:56 > 32:56

Therefore 5:8 is greater than 4:7
5:8 > 4:7

Q4
4:7 5:8 lcm of 8 n 7 56. so 8 x 7 = 56 5 x 7 = 40 40:56 then  4:7 7x8 = 56 and 4x8 = 32 32:56 so 5:8 is bigger i think

Q4 -
4: 7 = 4/7
5: 8=5/8
8 , 7 = no common factors , so
8×7=56
4/7×8/8 = 32/56
5/8×7/7= 40/56
32/56 < 35 / 56
= 4/ 7< 5/8
Thus , 4: 7 < 5:8

4:7 = (4/7) 4    x   8    =  32
------           ---------
7    x    8    = 56
5:8 = (5/8) 5   x   7  =  35
------         --------
8   x   7  = 56

32/56 < 35/56, so 5:8 is larger.
