The fraction 4/9 is equivalent to the repeating decimal 0.444..., while 3/8, 1/5, and 1/10 are terminating decimals. Thus, 4/9 is the correct choice for a repeating decimal.

The correct choice is 'a withdrawal of $152 followed by a deposit of $152' because these two opposite quantities cancel each other out, resulting in a total of 0.

-7/11 is a fraction, which is a type of rational number. Rational numbers are defined as numbers that can be expressed as the quotient of two integers, where the denominator is not zero. Thus, the correct term is 'rational number'.

To find the speed, divide the distance by the time. The cyclist rides 2.5 miles in 0.75 hours. Speed = 2.5 / 0.75 = 3.33 miles per hour, which is 3 1/3 miles per hour.

The equation y=12x indicates a direct proportionality where y increases by 12 for every unit increase in x. This matches the relationship described in the question, making B the correct choice.

The math club has 150 students, increasing by 10% to 165. The science club has 200 students, increasing by 15% to 230. Total this year: 165 + 230 = 395 students. Thus, the correct answer is C.

Let x be last year's drama club students. Then, x * 1.1 = 220, so x = 200. For the debate club, y * 1.2 = 264, so y = 220. Total last year = 200 + 220 = 420. Thus, the answer is B.

The baker frosts 4 1/2 cakes in 3/4 hour. To find the rate per hour, multiply by 4/3: (4.5 cakes) * (4/3) = 6 cakes. Thus, the baker can frost 6 cakes in 1 hour.

The expression 10+(−4)+5 indicates the water level starts at 10 cm, decreases by 4 cm in the first week, and then increases by 5 cm in the second week, confirming choice B as correct.

To find the speed, divide the distance by time. The car travels 7/8 mile in 1/4 hour. Speed = (7/8) / (1/4) = (7/8) * (4/1) = 7/2 miles per hour. Thus, the correct answer is 7/2 miles per hour.
