Question

A small plant is 2 1/2 inches tall. How tall will it be in 3 weeks if it grows 3/4 inch each week

Answer 1

it equals 1 7/8 bc 2 1/2= 5/2 x 3/4= 1 7/8

Answer 2

Here is you're answer:

In order to get the answer you need to add 3/4 + 3/4 + 3/4 then add that by 2 1/2.

• 
  `(3)/(4) + (3)/(4) + (3)/(4)`
• 
  `(3)/(4) + (3)/(4) = (6)/(4)`
• 
  `(6)/(4) + (3)/(4) = (9)/(4)`
• Now add:
• 
  `2(1)/(2) + (9)/(4)`
• Turn the mixed number into a improper fraction:
• 
  `2(1)/(2) = (5)/(2)`
• 
  `(5)/(2) + (9)/(4)`
• Find common denominator:
• 
  `CD = 4`
• 
  `= (14)/(4)`
• Simplify:
• 
  `(14)/(4) / 2 = (7)/(2)`
• Now turn into a mixed number:
• 
  `= 3(1)/(2)`

Therefore you're answer is "3 1/2."

Hope this helps!
