The answer is 1 1/4 because 1/2 is equal to 2/4 and 2/4 + 3/4 = 5/4. 5/4 is equal to 1 1/4. Hope this helps!
        
             
        
        
        
old (first visit): 550 grams
second visit: gained 350 grams
third visit: gained 300 grams
new: cora's kitten is now 1200 grams.
-> now, we must find the percent increase between 550 and 1200. 
to find percent increase, we use this equation
new - old / old x 100
-> (1200 - 550 / 550) x 100
    (650 / 550) x 100
    = 1.18 x 100
  <u>percent increase: 118% </u>
<u></u>
✧ hope this helped!

4/28 = 1/7 when dividing both numerator & denominator by 4 and this would be the simplified fraction.
You could use 1/7 to multiply with others to get other ratios that are equal to 4/28 or you could just use 4/28.
For example:
1/7 = 7/49
or
4/28 = 8/56
