Test: Fraction - 4 - Grade 4 MCQ

21/5 is not a proper fraction.

A/B = 1 is possible when A = B

To express 400 ml as a fraction of 1, we need to divide 400 by 1000 (since there are 1000 ml in 1 liter) to get the fraction.
So, 400 ml = 400/1000 = 4/10.
Therefore, the answer is A: 4/10.

To determine the odd one out among the given fractions, we need to find the fraction that doesn't fit the pattern of the others.
Looking at the fractions, we can see that all of them have a numerator less than the denominator except for option B: 3/5.
Therefore, the answer is B: 3/5.

To evaluate the given expression, we need to perform the operations in the correct order. Let's calculate step by step:
5 (2/3) - 3 (1/2) can be written as:
(5 * 2/3) - (3 * 1/2)
Multiplying the whole numbers with their respective fractions:
(10/3) - (3/2)
To subtract these fractions, we need to have a common denominator. The least common multiple of 3 and 2 is 6. Therefore, we can rewrite the expression as:
(10/3) * (2/2) - (3/2) * (3/3)
Multiplying the numerators and denominators:
(20/6) - (9/6)
Now that both fractions have the same denominator, we can subtract them:
(20 - 9) / 6 = 11/6
So the answer is B: 2 (1/6).

Looking at the options, we can see that all the fractions are correctly equivalent except for option C: 1/3 = 5/10. This is incorrect because 5/10 can be further simplified to 1/2 by dividing both the numerator and denominator by their greatest common divisor. So the answer is C: 1/3 = 5/10.
