Fraction Problems
Here are the answers:
4. The pieces of lace, when assembled together, is 13/14 meters long.
5. The girls have a combined lace that is 86/105 meters long.
Step-by-step explanation:
In the first problem, all you have to do is to get the LCD of 7 and 14, which is 14. Hence, the fractions will become 2/14 (formerly 1/7), 5/14 (no changes), and 6/14 (formerly 3/7). Since they have common denominators, just add all of the numerators. The answer will be 13/14 meters.
For the second problem, May has a 4/15 meter lace, while Lovie’s lace is 4/15 + 2/7 meters long. First, we need to find the LCD of 7 and 15, which is 105. Using the LCD, we can verify that the length of lace that May has is 28/105 meters, while Lovie has 58/105 meters. Add it together, and you’ll get 86/105 meters.
