What is ?, if ? × 2=1152

Answer: 576

Since ? × 2 = 1152, you reverse the multiplication by dividing: 1152 ÷ 2 = 576. None of the other options give 1152 when doubled.

How many students are required to type 700 pages in two days if two students who work part-time at a typing pool can do it in three days?

Answer: 3

Two students working for 3 days equals 2 × 3 = 6 student-days of work to type 700 pages. To complete that same amount of work in only 2 days, divide the total by the days: 6 ÷ 2 = 3 students. More students (4, 6, or 8) would finish the job faster than required.

answer to the expression 140/0.2

Answer: 700

Explanation: On each side of the quotient, the decimal point has an equal number of places to go. The result of multiplying both sides by ten is one step to the right. The product of both sides by 0.1 is equivalent to the division of both sides by 10, which is one step to the left. 140 / 0.2 = 1400 / 2 = 700

0.38 is the fraction that most closely approximates the given fraction in decimal form.

Answer: 3/8

Explanation: Finding the closest approximate decimal for each of the fractions in the response options is the simplest technique to resolve this kind of question. The number 3/6 can be written as 1/2, or 0.5. Since 3.5/7 would be the result of 3/7 minus 0.5, 3/7 must be just below 0.5. 3/8 is exactly 0.375 since 3/8 - 1/8 is 0.125. The remaining option should also be checked to make sure it is not closer to 0.38 than this one, even though it seems like the most logical choice. 3 out of 9 is equivalent to 1/3, or roughly 0.333. Thus, 3/8, is the appropriate response.

Convert 2/3 + 1/4 up to a decimal

Answer: 1.75

Explanation: You can resolve this problem by converting fractions to decimals: 3/2 + 1/4 = 1.5 + 0.25 = 1.75 As an alternative, you can first combine the fractions to form a single fraction by using the lowest common denominator, in this example 4: 3/2 + 1/4 = (3x2)/(2x2) + 1/4 = 6/4 + 1/4 = 7/4 = 1 3/4 = 1.75

Which of the following figures comes closest to the right response? 62 x 14 x 13

Answer: 9100

Explanation: We can resolve this issue by making a simple estimation given the wide range of magnitudes of the optional answers provided for this question. We could even attempt to round numbers 14 and 13 to 10 (!). In this situation, we would have the equation: 62 x 10 x 10. 10 x 10 = 100. The result of multiplying 62 by 100 is 6200. This amount is already a good deal higher than the previous three choices. The final result should be significantly higher and somewhere around 9000 as we rounded down 14 and 13 to 10. The right response is 9100.

Which of the following fractions has a decimal value that is the closest to 0.29?

Answer: 3/7

Explanation: You must first come up with a decimal value that is near to 0.29 and can be written as a simple fraction in order to answer this problem. The fraction 0.25, which may be written as either 1/4 or 2/8, is near to the number 0.29. Greater than 0.25 is 0.29. As a result, either the numerator or the denominator must be more than two or less than eight. The two answer options with the closest match are 2/7 and 3/7. 3/7, though, is more comparable to 1/2.
