Lily uses 1 3/4 of ribbon to make a knot. She wants to make 9 similar knots for her cousins. How many meters of ribbon does Lily need? Round your answer to the nearest meter.
1 3/4 ribbon??
Is that 1.75 meters?
16 meters
To determine how much ribbon Lily needs to make 9 similar knots, we need to find out the total amount of ribbon required for one knot and then multiply it by 9.
Lily uses 1 3/4 (or 7/4) of a ribbon for one knot.
To calculate the amount of ribbon needed for 9 knots, we can multiply 7/4 by 9:
(7/4) * 9 = 63/4
To convert this improper fraction to a mixed number, divide the numerator (63) by the denominator (4):
63 ÷ 4 = 15 remainder 3
This means that Lily needs 15 whole ribbons, each measuring 4 meters, and an additional 3/4 (or 0.75) of a meter.
Hence, the total amount of ribbon Lily needs is approximately 15.75 meters when rounded to the nearest meter.
