\text{Hey there!}

\mathsf{3\dfrac{1}{2}\times3\dfrac{1}{2}=?}

\mathsf{3\dfrac{1}{2}=3\times2+1=6+1=7}\\\\\mathsf{7\ becomes\ your\ numerator\ \& \ 2\ stays\  as\ your\ denominator}

\mathsf{\dfrac{7}{2}\times\dfrac{7}{2}=?}

\mathsf{Numerator \rightarrow Numberator}

\mathsf{Denominator\rightarrow Denominator}

\mathsf{\dfrac{7\times7\leftarrow numerator}{2\times2\leftarrow denominator}}

\mathsf{7\times7=49}\leftarrow\mathsf{NUMERATOR}

\mathsf{2\times2=4}\leftarrow\mathsf{DENOMINATOR}

\boxed{\boxed{\mathsf{Answer:\dfrac{49}{4}\ or\ 12\dfrac{1}{4}}}}\checkmark

Cant find the answer

Answer:

Carter family = 25 hours

Davis family = 31 hours

Step-by-step explanation:

Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.

So combined:

x + y = 45 hours

and we are also told that:

40x + 15y = 1300 L

So we can do simultaneous equations to solve the problem.

With some rearranging, we can figure out that:

y= 45 - x

and by substituting that into the second equation:

40x + 15 (45 -x) = 40x + 675 - 15x = 1300L

25x = 1300 - 675

25x = 625

x = 25 = hours that the Carter family used their sprinkler

and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:

25 + y = 56

y = 31

The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.
