The set of 4 consecutive integers that add up to 250 are 61, 62, 63, and 64.
61 + 62 + 63 + 64 = 250
For question A, the answer is 2. Since the sale sweatshirt if 40% LESS, this means that 60% of the original price still remains. 28.80 x .60 = 17.28
For question B, the answer if 4. You can divide 17 by 20 getting .85
2/8 divided by 1/4. Steps: 1. Division in math actually means multiplication. You just have to multiply by the reciprocal of the second fraction (reciprocal= denominator and numerator are switched). 2. Do 2/8 times 4/1. 3. 2 times 4= 8 and 8 times 1= 8
4. Your answer would be 8/8 which equals 1. This is how you divide fractions
