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.
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.
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.
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
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
