LCD stands for the least common denominator. 
The least common multiple of the denominators can be calculated as follows;
denominators are 2,16 and 8
divide all by 2      2/2 = 1       16/2 = 8        8/2 = 4
Divide by 2                    1        8/2 = 4         4/2 = 2
Divide by 2                    1        4/2 = 2         2/2 = 1
Divide by 2                     1        2/2 = 1           1
multiply - 2x2x2x2 = 16
16 is the least common multiple of 2,16 and 18
\frac{1}{2}  multiply both by 8 - \frac{8}{16}
\frac{3}{16} as it is
\frac{7}{8} multiply both by 2  - \frac{14}{16}
answer is 8/16,3/16,14/16

Grayson went to the grocery store and bought bottles of soda and bottles of juice. Each bottle of soda has 35 grams of sugar and
Illusion [34]

The number of bottles of soda purchased is 10 and the number of bottles of juice purchased is 4.

<u>Step-by-step explanation:</u>

Let us consider the soda bottles as x and juice bottles as y.

From the given data we can derive 2 equations,

35x+15y= 410.    .....(1)

x=y+6.                 ....(2)

Substitute equation (2) in (1),

35(y+6)+15y=410.

35y+ 210+15y=410.

50y+210=410.

50y=410-210.

50y=200.

y=4.

Substitute y value in equation (2),

x=4+6.

x=10.

The number of bottles of soda purchased is 10 and the number of bottles of juice purchased is 4.
