the second 3 (from the left) is in the hundreds place so we look at the 1st 7 (from the left) to determine how to round
since 7 is 5 or greater, we round the 3 to a 4

Answer:
0.9
Step-by-step explanation:
14/15 = 0.933333333 <u>IF:</u>
<u></u>
<u>1.</u><em> You first change it into a decimal by dividing the numerator by the denominator.</em>
<em> </em>14 ÷ 15
<u>2.</u> <em>You will get a recurring decimal.</em>
<em> </em>0.933333333
<u>3.</u><em> The first digit after the decimal is in the position of the '</em><u><em>tenths'</em></u>
0.<u>9</u>
<u>4.</u><em> You should use only two digits after the decimal to calculate </em>
<em> 0.93</em>
<u>5.</u><em> Since the number 3 is less than five, it will change into a zero and get eliminated.</em>
<em> ∴ The answer will be = 0.9</em>
