Answer: 7 1/12
B.
Step-by-step explanation:
Rewriting our equation with parts separated
=1+1/4+5+5/6
Solving the whole number parts
1+5=6
Solving the fraction parts
1/4+5/6=?
Find the LCD of 1/4 and 5/6 and rewrite to solve with the equivalent fractions.
LCD = 12 3/12+10/12= 13/12
Simplifying the fraction part, 13/12,
13/12=1 1/12
Combining the whole and fraction parts
6+1+1/12 = 7 1/12
so 9 times 8 is 72 so 155-72=83 and 83 divided by 6 equals 13.8333 but you can’t have .8333 delivery’s so you round it up to 14 so he needs to make at least 14 delivery’s to reach his goal of 155 delivery’s
This is what I got, hope this helped:)
