Share 1980 in the ratio 4:7

Let the shares be 4x and 7x

Now 4x + 7x = 1980

11x = 1980

x = 1980/11

x = 180

So the shares are

4x = 4 (180) = 720

7x = 7 (180) = 1260

Step-by-step explanation:

Rewrite the ratio in equation form:

4:7 = 4x+7x

Now write the equation with 1980 as the answer

4x+7x=1980

Simplify

11x=1980

now divide by 11 on both sides to isolate the variable

11x/11=x

1980/11=180

so x=180

180*4=720

180*7=1260

Check: 1260+720=1980
