Louise is creating a 1- foot long comic strip if she has marked 0.5 ft on her paper what should she do to find 1 foot?

Find a straight edge, mark the 0.5ft mark onto the straight edge that way it becomes a 0.5ft "ruler". Move the straight edge next to the mark and add another 0.5 ft.
It may seem unclear so if you have more questions you can ask in the comments :)

She should see how far she's gone then do that exact meausement she did, a second time, and youll find 1 foot, because 0.5 + 0.5 =1

5/7 ➗ 3/4

To divide the fractions you switch the numerator and denominator in the second fraction. By doing this you make the fractions multiply instead of divide.

So now the equation is

5/7 ✖️ 4/3

To get a common factor we will make the denominator of both of the fractions 21.

So now the equation is

15/21 ✖️ 28/21

To multiply fractions you multiply both numerators and both denominators.

So now the equation is

420/441

So to simplify the equation we divide the numerator and denominator by 21.

So now the equation is

20/21

So the question must be wrong or a trick question because the answer was correct.
