Question

How much do you need to subtract from 43/10 to make 4?

Answer 1

83/10

Explanation:

let x represent the number:

43/10 - x = 4

x = 4 + 43/10

simplifying the answer:

x = (4(10) + 43)/10

x = (40 + 43)/10

x = 83/10

`(43)/(10) - x = 4 \\`

`(43)/(10) - x = (40)/(10) \\`

Subtract sides 43 / 10

`- (43)/(10) + (43)/(10) - x = - (43)/(10) + (40)/(10) \\`

`- x = ( - 43 + 40)/(10) \\`

`- x = - (3)/(10) \\`

Negatives simplifies

`x = (3)/(10) \\`

Thus we need to subtract

`(3)/(10) \\`
