Answer:

15. a 7.9 miles

     b. NO .

Step-by-step explanation:

From the table, on

Monday = 3 2/5

Wednesday = 4 1/2

Write the distance in improper fractions as;

Monday = 17/5

Wednesday = 9/2

Find the sum as

\frac{17}{5} +\frac{9}{2} =\frac{34+45}{10} =\frac{79}{10}

where the L.C.M is 10

Answer is 7.9 miles

b.

Distance covered on Thursday and Saturday will be

2 2/6 + 3 3/4

14/6 + 15/4 ------the L.C.M is 12

(28+45)/12  

73/12

The distance 73/12 miles for Thursday + Saturday is less than that of Monday + Wednesday 79/10 miles. The answer is NO.

Whats the lcd of 1/7,14/17,12/13,5/6
gizmo_the_mogwai [7]
LCD (1/7, 14/7, 12/13, 5/6)

LCM = (7, 7, 13, 6)

=  2 * 3 * 7 * 13

=  546



1/7  = 78/546

14/7  = 1092/546

12/13  = 504/546

5/6  = 455/546




Calculation:

1/7 + 14/7 

= 1 + 14/7

=  15/7


The common denominator you can calculate as the least common multiple of the both denominators:   LCM (7, 7) = 7


Add:

15/7 + 12/13 

= 15 . 13/7. 13  + 12 . 7/13 . 7

= 195/91 + 84/91

=  195 + 84/91 

=  279/91


The common denominator you can calculate as the least common multiple of the both denominators:  LCM (7, 13) = 91



Add:

279/91 + 5/6

= 279 . 6/91 . 6 + 5 . 91/6. 91

= 1674/546 + 455/546

= 1674 + 455/546 

= 2129/546



The common denominator you can calculate as the least common multiple of the both denominators:  LCM (91, 6) = 546



Hence, 546 is the LCM/LCD of (1/7, 14/17, 13/13, 5/6).






Hope that helps!!!!!!
