You want the second number of all your ratios to be 3.

Divide the second number by 3, then use that quotient to divide both numbers.

12 : 9 ⇒ (12/3) : (9/3) = 4 : 3

24 : 12 ⇒ (24/4) : (12/4) = 6 : 3

3 : 1 ⇒ (3×3) : (1×3) = 9 : 3

28 : 21 ⇒ (28/7) : (21/7) = 4 : 3

40 : 24 ⇒ (40/8) : (24/8) = 5 : 3

36 : 12 ⇒ (36/4) : (12/4) = 9 : 3

48 : 18 ⇒ (48/6) : (18/6) = 8 : 3

28 : 12 ⇒ (28/4) : (12/4) = 7 : 3

A worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip. If the jugs are packed

Allisa [31]

Answer:

B. 2

Step-by-step explanation:

We have been given that a worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip.

Since worker has made 17 trips, so total number of hugs of liquid soap would be 17 times number of jugs carried per trip.

$17\times 4=68$ .

Since each carton holds 7 jugs, so number of cartoons would be $\frac{68}{7}$ .

$\frac{68}{7}\Rightarrow \frac{63+5}{7}=9\frac{5}{7}$

We can see that there are 9 completely filled cartoons and there are 5 jugs remaining, so we need $7-5=2$ jugs.

Therefore, we need 2 jugs to fill the 10th cartoon and option B is the correct choice.
