Fractional Numbers | MCQs

Explanation

To compare the fractions, convert them to equivalent decimals:

2/3 ≈ 0.67

5/8 ≈ 0.63

13/20 ≈ 0.65

Now, arrange the decimals in ascending order:

0.63, 0.65, 0.67

The corresponding fractions in ascending order are:

5/8, 13/20, 2/3

Explanation

Formula/rule for the series 8, 4, 2, 1, 1/2, 1/4, 1/8........

Explanation

Explanation

Value = 1/3 of 24

 =   1/3 x 24

  =  8

Explanation

To find the missing term in the sequence, let's examine the pattern:

1/3, 1/8, ?, 2/3

First, notice the denominators: 3, 8, ?, 3.

The denominators don't seem to follow a straightforward arithmetic or geometric progression. Let's look at the numerators:

1, 1, ?, 2

The numerators seem to increase by 1 each time.

If we consider that the numerators increase by 1 and the denominators are not following a clear pattern, we could assume a pattern where the numerators increase by 1 every two terms.

Following this pattern, the missing term should have a numerator of 1, and since it's the second term after 1/8, the denominator should be 5 (since 3 + 2 = 5).

So, the missing term is 1/5.

Therefore, the completed series is:

1/3, 1/8, 1/5, 2/3

Explanation

34 is correct answer because if you multiply 3X17= 51 and than 2X17= 34

Explanation

4x/12 = 42

4x = 42*12 = 504

X = 504/4 = 126

8/14 * 126 = 8*9 = 72

Explanation

The additive inverse of a number is the number that, when added to it, results in zero.

For -3/a, the additive inverse is:

3/a, since (-3/a) + (3/a) = 0
