Unformatted text preview: 3.4 254 26 1 2/30 + 3 9/30 – 2 24/30 = 3 41/30 – 2 24/30 = 1 17/30 255 30 5 4/12 + 2 3/12 + 3 6/12 = 10 13/12 = 11 1/12 257 48 14 2/8 – 12 3/8 = 13 10/8 – 12 3/8 = 1 7/8 % 3.5 265 14 120 * 1/50 = 120/50 = 12/5 = 2 2/5. He should allow 2 per hour, or 12 each 5 hours. 16 \$3 * ½ * 20 = \$3/2 * 20 = \$30 24 To estimate, 17 11/12 is slightly less than 18, and 6 1/10 is slightly more than 6, so the quotient is slightly less than 18/6 = 3. Solving exactly, 215/12 ÷ 61/10 = 215/12 * 10/61 = 215/6 * 5/61 = 1075/366 = 2 343/366.
