Ineed me i stuck and i don’t want to get it wrong

9/28 of the lawn still needs to be mowed, and the son mowed more.

Step-by-step explanation:

I am assuming it was he mowed 1/4 of the lawn, and his son moved 3/7 of the lawn (the font is kinda small). To find out how much of the lawn still needs to be mowed, we need to find 1 - (1/4 + 3/7). To find 1/4 + 3/7, let's find the LCM (least common multiple) of the denominators. This can be found by skip-counting, and you will get 28. Now, convert each denominator to 28 to get 7/28 + 12/28 = 19/28. Now we need to find 1 - 19/28, which is just 9/28.

To find who mowed more, let's go to where i said convert each denominator to 28. When I do this, I get the two values 7/28 and 128/28, and from here it is easy to see that the son mowed more.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

one of these should be correct

it has changed from the width and the height.
