liberstina [14]
First, write the rate as a decimal by moving the decimal point two places to the left from the percent.

r = 5% = 0.05

C = p + rp

C = 30.99 + 0.05 * 30.99

C = 30.99 + 1.55

Which is the best for the sum 2/9+10/11?a. 0+0=0 b.1/2+1/2=1 c. 1+1=2d. 0+1=1
Sloan [31]

You have the following expression:

\frac{2}{9}+\frac{10}{11}

By definition, when you want to express a fraction as a decimal number, you must divide the numerator by the denominator. Knowing this, you get the following:

\begin{gathered} \frac{2}{9}\approx0.22 \\  \\ \frac{10}{11}\approx0.90 \end{gathered}

You can identify that:

\begin{gathered} 0.22\approx0 \\ 0.90\approx1 \end{gathered}

Based on the above, you can determine that the best estimate for the sum is:

\frac{2}{9}+\frac{10}{11}\approx0+1=1

The answer is option d:

0+1=1
