Which symbol makes this true?   7/8 ___ 4/8\nA. =    B. >    C. <    D. +\nAnswer Key\n#\nAnswer\nExplanation\n1\nC. 1/4\nOne slice is 1 of 4 equal parts, so it is 1/4 of the pizza.\n2\nB. 1/6\nA unit fraction has 1 as its numerator, and 1/6 is the only choice with a 1 on top.\n3\nA. 1/3\nThe first mark after 0 shows 1 of the 3 equal parts, which is 1/3.\n4\nD. Third mark after 0\nWith 4 equal parts, each mark is one more fourth, so the third mark is 3/4.\n5\nD. 1/2\nBoth fractions have 1 part, but halves are bigger pieces than eighths, so 1/2 is greater.\n6\nC. 3/6 < 5/6\nThe pieces are the same size (sixths), so 3 pieces is less than 5 pieces.\n7\nD. 1/6\nWith the same numerator, the bigger the denominator, the smaller each piece, so 1/6 is smallest.\n8\nA. Maria\nBoth ate 2 pieces, but thirds are bigger than fifths, so 2/3 is more than 2/5.\n9\nC. Halfway between 0 and 1\n1/2 means one of two equal parts, so it sits right in the middle of 0 and 1.\n10\nB. >\nThe pieces are both eighths, and 7 pieces is more than 4 pieces, so 7/8 > 4/8.\n", "capture_note": "Claude's chat reply, then the Claude Docs document text as copied (tables copy as one cell per line; document links copy as plain text)"}
