Question

Sandra has ribbons that are 2/6 meter 3/4meter and 4/9 meter long .She needs to use the ribbon longer than 2/3meter to make a bow. Which length of ribbon can she use for the bow?

Answer 1

Answer:

3/4 meter

Step-by-step explanation:

Need Common denominators to compare size

2/6  3/4  4/9     which is longer than 2/3?

2/6 compared to 2/3.  2/6 = 2/6 and 2/3 = 4/6.  

2/6 < 2/3 so 2/6 is too short

3/4 compared to 2/3   3/4 = 9/12  and 2/3 =  8/12

3/4 > 2/3 so 3/4 is longer than 2/3

4/9 compared to 2/3  4/9 = 4/9 and 2/3 = 6/9

4/9 < 2/3 so 4/9 is too short

Answer 2

Correct answer: She can use the bow with the length of 3/4

Explanation: when you divide 2/3 you get a continuous 0.6 so now you know that when you divide the rest of the lengths you need to find the answer which length is greater than 0.6. For example, 2/6 (2 divided by 6) = 0.3 so that is out. 4/9 (4 divided by 9)= 0.4 so that is out as well and as for 3/4 (3 divided by 4)= 0.75 which is greater than 0.6 and makes your answer of 3/4 correct.

Have a great day :)
