How long are the pieces of lace together?
5) May has 4/15 meter of lace while Lovie has 2/7 meter longer than May’s
lace. How many meters of lace do girls have altogether?​

Answer:

13/14

Solution:

[tex]\frac{1}{7} + \frac{5}{14} + \frac{3}{7} = \frac{1}{7}(\frac{2}{2}) + \frac{5}{14} + \frac{3}{7}(\frac{2}{2}) = \frac{2}{14} + \frac{5}{14} + \frac{6}{14} = \frac{2 + 5 + 6}{14} = \frac{13}{14}[/tex]

Answer:

86/105

Solution:

Let x be the length of Lovie’s lace

Let y be the sum of the meters of lace of May and Lovie

x = [tex]\frac{2}{7} + \frac{4}{15}[/tex] = [tex]\frac{58}{105}[/tex]

y = [tex]\frac{4}{15}[/tex] + x

y = [tex]\frac{4}{15}[/tex] + [tex]\frac{58}{105}[/tex]

y = [tex]\frac{86}{105}[/tex]
