Answer:  2.3 × 0.4 = 0.92 .

2.3 × 1 = 2.3

0.92 + 2.3 = 3.22

Step-by-step explanation:

When decimal points are left out until the end, you can count the number of decimal places to the right of the decimals in the factors and then insert the decimal in the product, counting places right <u><em>to left.</em></u>

The factor 2.3 has one decimal place. The factor 0.4 has one decimal place.

Thats a total of 2.

92 becomes .92 when the decimal is inserted <u><em>two places to the left.</em></u>

230 becomes 2.30 when the decimal is inserted <u><em>two places to the left.</em></u>

Answer:

\frac{\sqrt{17}}{4}

Step-by-step explanation:

Rationalizing the denominator of a fraction is when one multiplying fraction such that it removes any radical from the denominator. This can be done by multiplying both the numerator and the denominator by the radical that is present in the denominator. In fractional terms, a number over itself is equal to one, therefore, doing this would keep the equation true. After multiplying, one will simplify the resulting fraction.

\frac{17}{4\sqrt{17}} * \frac{\sqrt{17}}{\sqrt{17}}\\\\= \frac{17\sqrt{17}}{4(17)}\\

Simplify like factor found in both the numerator and the denominator,

\frac{17\sqrt{17}}{4(17)}\\\\= \frac{\sqrt{17}}{4}
