Lily uses 1 3/4 meters 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.
I love thames
15 3/4 is the answer right???????!!!!!11
1 3/4 = 7/4
7/4 * 9 = ?
1 3/7=7/4
I dont get it pls expln.
To find out how many meters of ribbon Lily needs, we need to multiply the length of one knot by the total number of knots she wants to make.
First, we need to change the mixed number 1 3/4 into an improper fraction. To do this, we multiply the whole number (1) by the denominator (4) and add the numerator (3). In this case, the improper fraction is (1 * 4 + 3) / 4 = 7/4 meters.
Next, we multiply the length of one knot (7/4 meters) by the total number of knots (9). To multiply fractions, we multiply the numerators (7 * 9 = 63) and multiply the denominators (4 * 1 = 4) separately. This gives us the fraction 63/4 meters.
To round the answer to the nearest meter, we divide the numerator (63) by the denominator (4). The result is 15.75 meters.
Finally, we round 15.75 meters to the nearest meter, which is 16 meters.
Therefore, Lily needs approximately 16 meters of ribbon to make 9 similar knots for her cousins.
