Explanation

To compare fractions, convert them to decimal values:

7/9 = 0.777

5/6 = 0.833

8/9 = 0.888

8/7 = 1.142

The smallest value among them is 7/9.

Explanation

The equation 3(4x) = (4x)3 shows that the order of multiplication does not affect the result.

This is the Commutative Property of Multiplication, where a × b = b × a.

Explanation

To find 3/7 of 14:

(3/7) * 14 = 3 * 2 = 6

Explanation

The sum of two whole numbers is always a whole number — this is called closure property of addition.

Whole numbers include 0 and all positive integers (0, 1, 2, 3, ...).

Explanation

To find the quotient, we need to divide the two fractions:

(64/63) ÷ (108/117)

= (64/63) × (117/108)

= (64 × 117) / (63 × 108)

= 7488 / 6804

= 208 / 189

Explanation

To check if a number is exactly divisible by 4, we can check if the last two digits form a number that is divisible by 4.

2000: Last two digits are 00, which is divisible by 4.

Since 2000 ends in 00, it is exactly divisible by 4.

Explanation

 Third integer is x + 4 = 11 + 4 = 15. 

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Multiply the numerators (numbers on top):

1 × 3 × 6 = 18

Multiply the denominators (numbers on the bottom):

10 × 5 × 5 = 250

Write the result as a fraction:

18/250

Simplify the fraction by dividing both numbers by their greatest common divisor (GCD), which is 2:

18 ÷ 2 = 9

250 ÷ 2 = 125

So, the simplified result is:

9/125

Explanation

= (25/100)*25

= (25*25)/100

= 625/100

= 6.25

Explanation

√0.49 = √(49/100)

= √49 / √100

= 7/10

= 0.7
