It means $$\frac{80}{100}$$ . 16- Choice A is correct The correct answer is $$62$$To find the answer subtract $$58$$ from $$120$$. The answer is $$(120 \ – \ 58 = ) \ 62$$. 17- Choice D is correct The correct answer is $$12$$$$25 \ + \ B \ + \ 6 = 43 ⇒ 31 \ + \ B = 43 ⇒ B = 43 \ – \ 31 = 12$$ 18- Choice C is correct The correct answer is $$\ ×$$$$2 \ × \ 8 = 16$$. Then:$$2 \ × \ 8\ ⎕ \ 4 = 64$$$$16\ ⎕ \ 4 = 64 ⇒ 64 = 16 \ × \ 4$$ 19- Choice D is correct The correct answer is $$650$$We round the number up to the nearest ten if the last digit in the number is $$5, \ 6, \ 7, \ 8,$$ or $$9$$.We round the number down to the nearest ten if the last digit in the number is $$1, \ 2, \ 3,$$ or $$4$$.If the last digit is $$0$$, then we do not have to do any rounding, because it is already rounded to the ten.Therefore, rounded number of $$645$$ to the nearest ten is $$650$$. 20- Choice D is correct The correct answer is $$80$$$$2$$ spaghetti with meatballs cost: $$2 \ × \ 15 = 30$$$$5$$ bowls of bean soup cost: $$5 \ × \ 10 = 50$$$$2$$ spaghetti with meatballs $$+\ 5$$ bowls of bean soup cost: $$30 \ + \  50= 80$$ 21- Choice A is correct The correct answer is $$750$$ $$50 \ × \ 15 = 750$$ 22- Choice C is correct The correct answer is $$90$$$$15 \ × \ 6 = 90$$ 23- Choice B is correct The correct answer is $$525 \ - \ 266\ - \ 100 =$$_____Liam gave $$266$$ of his marbles to his friend. Now he has $$525 \ – \ 266 = 259$$He lost $$100$$ of his marbles.Now, he has $$259 \ – \ 100 = 159$$ or $$(525 \ – \ 266 \ – \ 100)$$. 24- Choice A is correct The correct answer is $$73$$$$4$$ rows that have $$12$$ red cards in each row contain: $$4 \ × \ 12 = 48$$ red cardsAnd there are $$25$$ white cards on table. Therefore, there are $$48 \ + \ 25 = 73$$ cards on table. 25- Choice D is correct The correct answer is $$35$$If Alex eats $$5$$ meals in $$1$$ day, then, in a week ($$7$$days) he eats $$(7 \ × \ 5 = 35)$$ meals. 26- Choice C is correct The correct answer is $$7$$Perimeter of the square is $$28$$. Then:$$28 = 4 \ × \$$side ⇒ side $$=$$ $$7$$Each side of the square is $$7$$ units. 27- Choice A is correct The correct answer is $$\frac {12}{8}=\frac{3}{2}$$Simplify  $$\frac{3}{2}$$ that’s equal to $$\frac{12}{8}$$ Only option A is correct. 28- Choice B is correct The correct answer is $$8 \ \frac{1}{2}$$This shape shows $$8$$ complete shaded rectangle and a half of a rectangle. It is equal to $$8 \ \frac{1}{2}$$ . 29- Choice C is correct The correct answer is Bryan,  Longview,  Mission,  EdinburgBryan city with $$80,110$$ has the least population. Longview, Mission and Edinburg are other cities in order from least to greatest. 30- Choice A is correct The correct answer is $$\frac{12}{8}, \frac{24}{16}, \frac{48}{32}$$All these fractions; $$\frac{12}{8}, \frac{24}{16}, \frac{48}{32}$$ are equivalent to  $$\frac{3}{2}$$
