What is 16% of 43 minutes? Round answer to tenths place.

sergiy2304 [10]

Answer: $6.9\ minutes$

Step-by-step explanation:

Let "x" represents the 16% of 43 minutes.

Once you analize the information given in the exercise, you can identify that 43 minutes is the 100%.

Then, with this data, you can set up the following proportion:

$\frac{100}{43}=\frac{16}{x}$

Now you must solve for "x". The steps are:

- Multiply both sides of the equation by "x"

$(x)(\frac{100}{43})=(\frac{16}{x})(x)\\\\\frac{100x}{43}=16$

- Multiply both sides by 43:

$(43)(\frac{100x}{43})=(16)(43)\\\\100x=688$

- Divide both sides by 100:

$\frac{100x}{100}=\frac{688}{100}\\\\x=6.88$

- Rounding to the tenths place:

$x\approx6.9$
