Question

2/5+3/5:x=7/10 

Answer 1

3/5:x=7/10-2/5

3/5:x=7/10-4/10

3/5:x=3/10

x=3/5:3/10

x=3/5 x 10/3

x=10/5

x=2

Answer 2

2/5 + 3/5 : x = 7/10 

3/5 : x = 7/10 - 2/5

3/5 : x = 3/10

x = 3/10 x 3/5

x = 9/50.

Answer 3

`2/5+3/5:x=7/10 `

`3/5:x=7/10-2/5`

`3/5:x=7/10-4/10`

`3/5:x=3/10`

`x=3/5:3/10`

`x=3/5xx10/3`

`x=1/2`

Answer 4

\(2/5+3/5:x=7/10 \)

\(3/5:x=7/10-2/5=3/10\)

\(x=3/5:3/10\)

\(x= 30/15\) \(=1/2\)
