Answer 1

[8]

`a, x = 8/5 : 3/7`

`x = 56/15`

`b, x xx 4/15 = 6/7`

`x = 6/7 : 4/15`

`x = 45/14`

`c, x = 7/4 xx 4/9`

`x = 7/9`

`d, x = 6/5 + 7/15`

`x = 5/3`

`e, x=  7/4 - 3/8`

`x = 11/8`

`f, x = 15/19 : 4/3`

`x = 45/76`

`g, x = 15/4 - 21/12`

`x = 2` 

Answer 2

a)Xx3\7=8\5;    b)Xx4\15=6\7;     c)x:4\9=7\4        d)x-7\15=6\5       

e)3\8+x=7\4:     g)15\19:x=8\5-4\15                      

a) X \(\times\)`3/7` = `8/5`

X = `8/5` : `3/7`

X = `56/15`

b) X \(\times\) `4/15` = `6/7`

X = `6/7` : `4/15`

X = `45/14`

c) X : `4/9` = `7/4`

X = `7/4` \(\times\) `4/9`

X = `7/9`

d) X - `7/15` = `6/5`

X = `6/5` + `7/15`

X = `5/3`

e) `3/8` + X = `7/4`

X = `7/4` - `3/8`

X = `11/8`

g) `15/19` : X = `8/5` - `4/15`

`15/19` : X = `4/3`

X = `15/19` : `4/3`

X = `45/76`

h) `15/4` - X = `5/12` + `4/3`

`15/4` - X = `7/4`

X = `15/4` - `7/4`

X = 2.

Answer 3

a: x=8/5:3/7=8/5x7/3=56/15

b: x=6/7:4/15=6/7x15/4=90/28=45/14

c: x=7/4x4/9=7/9

d: x=6/5+7/15=18/15+7/15=25/15=5/3

e: x=7/4-3/8=11/8

Answer 4

`x xx 3/7=8/5`

`->x=8/5:3/7=56/15`

`x xx4/14=6/7`

`x=6/7:4/14`

`x=6/2=3`

`x:4/9=7/4`

`x=7/4xx4/9`

`x=7/9`

`x-7/15=6/5`

`x=6/5+7/15`

`x=25/15=5/3`

`3/8+x=7/4`

`x=7/4-3/8`

`x=11/8`
