Question

A mass of 380kg when divided in the ratio of 1:3:4, is​

Answer 1

Answer:

47.5kg:142.5kg:190kg

Step-by-step explanation:

Frist you have to create an equation.  

So the equation would be:

1x+3x+4x=380

 

your coefficients repsent the ratio.  

 

The next step is to combine like terms:

therefore 1x+3x+4x

becomes

8x

so the equation is now:

8x=380

The next step is to divide 8 on both sides.  

So (8x/8)=(380/8)

which leaves you with  

x=47.5

now we plug x into:

1x which gives us 47.5

3x which gives us 142.5

4x which gives us 190

when you add these three together you get 380

 

therefore your answer is

47.5kg:142.5kg:190kg
