20% of what number is 18
Explain.

Answers

In this question, the thing that needs to be found is the number whose 20% would be 18. The information's required for getting to the solution are already provided in the question. based on those given information's, the answer can be deduced very easily.
Let us assume the unknown number to be = x
Then
(20/100) * x = 18
x/5 = 18
x = 18 * 5
   = 90
so the unknown number in the question is 90. I hope the procedure is clear enough for you to understand.

The number represented by 20% of 18 is 90.

To find out what number is represented by 20% of 18, set up an equation.

Let "x" be the unknown number  are trying to find.

The word "of" in mathematics typically indicates multiplication. So, "20% of x"  represented as 0.20 × x or simply 0.20x.

Now, the problem states that 20% of this unknown number (0.20x) is equal to 18:

0.20x = 18

To find the value of "x," to isolate it on one side of the equation. To do that, divide both sides of the equation by 0.20:

x = 18 ÷ 0.20

x = 90

my dad is 40 miles away at work...if he leaves work at 6:24pm...and travels at an average of 43 miles per hour...what time is he at home? plz help

Answers

If his speed is 43 mph, then it takes him 40/43 of an hour to go 40 miles.

An hour = 60 minutes.

40/43 of 60 minutes = 55.8 minutes. He gets home 55.8 minutes after 6:24 PM.
Travel 40 miles at a rate of 43 miles per hour equals 40/43 = 0.93 hr = 55.81 min. round up to 56 min.

So take 56 min added to 6:24pm equals 7:20pm approx.

Thanks for the entertainment.
