Three friends each have some ribbon. Carol has 42 inches of ribbon, Tino has 2.5 feet of ribbon, and Baxter has 1.5 yards of ribbon. Express the total legth of ribbon the three friends havein inches, feet and yars.
**We are learning to use Unit Rates & Conversion Factors to solve these problems.
THANK YOU!
well, lets do it all in inches first
42 in + 2.5 ft (12 in/ft) + 1.5 yds(36 in/yd)
= 42 + 30 + 54 = 126 inches
126 in (1 ft/12 in) = 10.5 feet
10.5 ft (1 yd/3 ft) = 3.5 yards
To express the total length of ribbon the three friends have in inches, feet, and yards, we first need to convert all the measurements to the same unit.
1. Convert Carol's 42 inches to feet:
There are 12 inches in 1 foot, so we divide 42 by 12:
42 inches / 12 inches/foot = 3.5 feet
2. Convert Tino's 2.5 feet to yards:
There are 3 feet in 1 yard, so we divide 2.5 by 3:
2.5 feet / 3 feet/yard = 0.83 yards
3. Baxter's measurement is already in yards, so no conversion is necessary.
Now that we have all the measurements in yards, we can find the total length:
Total length in yards = Carol's length + Tino's length + Baxter's length
= 0 yards + 0.83 yards + 1.5 yards
= 2.33 yards
To convert this total to inches and feet, we use conversion factors:
1 yard = 36 inches
1 yard = 3 feet
To find the total length in inches:
Total length in inches = Total length in yards * Conversion factor for yards to inches
= 2.33 yards * 36 inches/yard
= 83.88 inches (approx.)
To find the total length in feet:
Total length in feet = Total length in yards * Conversion factor for yards to feet
= 2.33 yards * 3 feet/yard
= 7 feet (approx.)
So, the three friends have a total length of approximately 83.88 inches, 7 feet, and 2.33 yards of ribbon.
Suzanna wants to measure board , but she doean't have a ruler to measure with. However , she does have several copies of a book that she knows is 17 centimeters tall.First question suzanna lays the books end to end and finds that the board is the same length as 21 books. How many centimeters long is the board
the ancre is
