Let’s break down the two questions:<\/p>\n\n\n\n
Question 1: Sterling Silver Composition<\/h3>\n\n\n\n
Sterling silver is composed of 92.5% silver and 7.5% copper. The question asks for the decimal representation of the portion of silver in sterling silver.<\/p>\n\n\n\n
To convert a percentage into a decimal, divide the percentage by 100. So for 92.5%, we do the following calculation:92.5\u00f7100=0.92592.5 \\div 100 = 0.92592.5\u00f7100=0.925<\/p>\n\n\n\n
So, the decimal that represents the portion of silver in sterling silver is 0.925<\/strong>.<\/p>\n\n\n\n Correct Answer: A. 0.925<\/strong><\/p>\n\n\n\n We are given the expression:10+(66\u221262)10 + (66 – 62)10+(66\u221262)<\/p>\n\n\n\n To evaluate this expression, we must follow the Order of Operations<\/strong> (also known as PEMDAS or BIDMAS):<\/p>\n\n\n\n Thus, the first thing to do is to evaluate the expression inside the parentheses<\/strong>.<\/p>\n\n\n\n Correct Answer: First, subtract 66 – 62 inside the parentheses.<\/strong><\/p>\n\n\n\n In this problem, following the correct order of operations ensures that the evaluation is performed accurately. If we didn’t simplify the parentheses first, we would get an incorrect result.<\/p>\n\n\n\n Spiral Review (CC.6.RP.3c, CC.6.RP.3d, CC.6.EE.1, CC.6.E 3.
