If π equals twenty-one point four, π equals twenty-three point four,
and π equals nine, evaluate π plus π plus π all divided by π to the
nearest tenth.

In order to evaluate our expression, π plus π plus π divided by π, we
need to take our values for π, π, and π and plug those into our expression. We will replace π with the value twenty-one point four. Replace π with the value nine. And replace both πβs with the value twenty-three point
four.

Now we need to simplify. First we need to add all the numbers on our numerator to
simplify our numerator. The numerator is the top portion of your fraction, so letβs add twenty-one
point four plus nine plus twenty-three point four. This results in fifty-three point eight. divided by twenty-three point four,
which equals two point two nine nine one four five three. However, it
tells us to round to the nearest tenth. The first place value to the right of the decimal is our tenths place. So when it
says to round to the nearest tenth, our final answer should be ending in a tenths
place.

So we need to decide how to round. We must look at the place value to the right of the one that weβre rounding to in
order to decide whether to keep our two a two or two rounded up to a three. So we look at the
hundredths place. Thatβs where the nine is. Number zero through four would keep the two the same. Numbers five through nine
would make the two round up to a three. So since nine is our- in our hundredth place and weβre
rounding to the tenths place, our two will turn into a three. So our final answer is two point three.
