In science experiment a plant grew 3/4 inch one week and 1/2 inch the next week use a common denominator to write an equivalent fraction for each fraction

Both fraction have a common denominator.

Thus, Length of plant increases in one week

and Length of plant increases in next week .

Step-by-step explanation:

Given : Length of plant increases in one week

also,  Length of plant increases in next week

Equivalent fraction are fractions having same value, even though they may look different.

Here, we have to use a common denominator to write an equivalent fraction.

Thus, multiply the denominator and numerator by 2 of the length of plant increases in next week  that is,

Thus, both fraction have a common denominator.

Thus, Length of plant increases in one week

and Length of plant increases in next week .

idk what the heck he answer is, i’m just putting this here so i finish my account

add 8+12 to get a simplified answer of 12r-20
