She will need 6/8 because 3/4 the cup is divided into 8 so we need the denominator to be 8. we multiply 4 x 2 and what every we do to the top happens to the bottom so we also multiply 3 x 2. then we see that sara needs 6/8 cups of dish soap to make her bubbles
To find the area of this just add the units I believe which is 21 Hope this helps good luck. Not sure if this is 100% right my last year teacher was a sucky one
