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.

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
