Answer:
The ratio of the white fabric to the colored fabric is [tex]\frac{20}{9}[/tex] in its simplest form
Step-by-step explanation:
The ratio indicates how many times one number contains another
The ratio can be written as:
The two terms of the ratio must have the same units
∵ Sarah uses 9 mm of colored fabric to make her curtains
∵ She also uses 2 cm of of white fabric
- To express the amount of white fabric to colored fabric as a ratio
you must change the centimeter to millimeter because the
terms of ratio must have the same unit
∵ 1 centimeter = 10 millimeters
∴ 2 centimeters = 2 × 10 = 20 millimeters
∴ She uses 20 millimeters of the white fabric
Now write the ratio between the white fabric and the colored fabric
→ White : colored
→ 20 : 9
∵ 20 and 9 do not have a common factor
∴ The simplest form of the ratio is 20 : 9
The ratio of the white fabric to the colored fabric is [tex]\frac{20}{9}[/tex] in its simplest form
