Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.

With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.

Answer : It'll take 3.43 hours to do the job if they work at the same rate.
Hope this helps. - M
Answer:
t = 4
Step-by-step explanation:
13 + t = 17
t = 4
13 + 4 = 17
An easier way to solve a question like this is to subtract the number given by the answer.
Example:
17 - 13 = 4
The answers are A, B, and D.
The given information is that Tomas needs 6 potatoes to make 12 potato pancakes. Thus, we can assume it takes 1 potato to make 2 potato pancakes.
An answer choice must have two times more pancakes than potatoes. Only A, B, and D satisfy this. The others can be confusing if the multiplication is not executed properly.
Percent of decrease :
Original - New / Original
so...
80 - 52 / 80 ---->
28/80
.35 multiply by 100 to get percent
35% increase Hope I helped if you have any questions let me know! :)
A = 2
b = -5
c = 6
The coefficients are 2 and -5
The constant is 6
