(1) What is the quotient of the sum of 14 and 18 in addition to their difference? (2) Eight times of a number plus 6.8 equals 60% of 74. What's the number? (solved by equation)
(1) (14-18) / (14 + 18), = 18 △ 38, = 13. Answer: the quotient is 13. (2) let this number be x, we can get the equation: 8x + 6.8 = 74 × 60%. 8x + 6.8 = 44.4, & nbsp; & nbsp; & nbsp; 8x = 37.6, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 4.7. Answer: this number is 4.7
