Answer 2

Answer:

iii) 2/7 + 1/4

= LCM of 7 and 4 = 28

= 2/7 = 8/28

1/4 = 7/28

= 8+7/28

16/28 = 8/14 = 4/7

iv)3/5 + 3/8

= LCM of 5 and 8 =40

= 3/5 = 24/40

3/8 = 15/40

= 24+15/40

= 39/40

v) 6/5 + 1/2

= LCM of 5 and 2 = 10

6/5 = 12/10

1/2 = 5/10

= 12+5/10

17/10

vi) 2/12 + 2/4

= LCM of 12 and 4 = 12

2/12 = 2/12

2/4 = 6/12

= 2+6/12

= 8/12

Q3)

i) 3 2/8 x 9/10

3 2/8 = 3 x 8 +2 /8

= 26/8

= 26/8 x 9/10

= 26 x 9 / 8 x 10

= 234/90

ii)1 2/4 x 5/6

1 2/4 = 1 x 4 + 2 / 4

= 6/4

= 6/4 x 5/6

= 6x5 / 4x6

= 30/24

iii) 2 4/10 x 4/5

2 4/10 = 2 x 10 + 4 = 24/10

= 24/10 x 4/5

= 24x4 / 10x5

=96/50

iv) 3 1/4 x 2/6

3 1/4 = 3x4+1/4 = 13/4

= 13/4 x 2/6

= 13 x 2/4 x 6

=26/24

v)   3 1/5 x 4/9

3 1/5 = 3x5+1/5 = 16/5

= 16 x 4/5 x 9

= 64/45

vi) 3 1/8 x 1/9

3 1/8 = 3 x 8 + 1 /8 = 25/8

= 25 x 1/8 x 9

=25/72

Q 4 )

i) 44/100 = 176/? = 220/?

176/? = 176/44 = 4

so 44 x 4 / 100 x 4

= 176/400

44/100 = 176/400 = 220/?

220/? = 220/176 = 1.5

= 176 x 1.5/400 x 1.5

= 220/600

So 44/100 = 176/400 = 220/600
