Answer 1

Solution

Given,

• what number must be added to the ratio 7 : 5 so that the ratio become 5:4

To find ,

• we have to find here the number

Now,

• Let the number be "x"
• So, 7:5 = 7/5 and inter question it is given that what number should be added to the ratio 7:5 to become 5:4 .
• So, the equation will be like this ; 7+x/5+x = 5/4

now solving this we get ;

$= > \frac{7 + x}{5 + x} = \frac{5}{4}$

$= > 4(7 + x) = 5(5 + x)$

$= > 28 + 4x = 25 + 5x$

$= > 28 - 25 = 5x - 4x$

$= > 3 = x$

So, the number 3 will be added to the ratio to get 5:4 .
