Emily has 3 1/2 liters if juice. She poured 1 3/4 liters of juice into glasses. How many liters of juice left to emily? Please need help

1 3/4

Step-by-step explanation:

Convert the mixed fractions to fractions.  This will make it easier to subtract.

3 1/2  =  7/2

1 3/4  =  7/4

Now make the fractions have a common denominator.  To do this, you need to multiply the denominator by a number that will make it equal to the other number.  For this case, it is 2.  So that the value of the number doesn't change, you need to multiply the numerator by 2 as well.  This means that you are multiplying this equation by 2/2.  This is equal to 1 since the numerator and denominator are the same number.

1 = 2/2

(7/2)(2/2) = 14/4

Now subtract the two fractions.

14/4 - 7/4 = 7/4

Now convert back to a mixed fractions.

7/4  =  1 3/4

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
