Explanation

To divide a number by 100, you can simply move the decimal point two places to the left:

0.26 ÷ 100 = 0.0026

Explanation

A number that is divisible by both 4 and 9 must be a multiple of their least common multiple (LCM), which is 36.

5256 is the only number that is a multiple of 36 (5256 = 36 × 146).

Explanation

The sum of the internal angles of a polygon can be found using the formula:

(n-2) × 180°

where n is the number of sides.

For a regular octagon (8 sides):

(8-2) × 180° = 6 × 180° = 1080°

Since it's a regular octagon, all internal angles are equal. To find the measure of each internal angle, divide the total sum by the number of angles:

1080° ÷ 8 = 135°

Explanation

The given series is a square of natural number

(1)^2 = 1

(2)^2 = 4

(3)^2 =9

(4)^2 = 16

(5)^2 = 25

Explanation

To find the percentage of boys, divide the number of boys (56) by the total number of students (140), and then multiply by 100:

(56 ÷ 140) x 100 = 0.4 x 100 = 40%

So, the percentage of boys is 40%.

Explanation

To convert 18 (decimal) to octal:

18 ÷ 8 = 2 remainder 2

2 ÷ 8 = 0 remainder 2

Reading the remainders from bottom to top, 18₁₀ = 22₈.

Explanation

The pattern of the series is:

+1, +2, +3, +4, +5...

So, the next difference should be +6:

16 + 6 = 22

The correct answer is 22.

Explanation

If a month starts with Sunday, then the number of Sundays in that month is 5

The remaining days is 30−5=25

Given that average number of visitors on Sundays is 510

Therefore, 510=5sum of the number of visitors on Sundays​

⟹sum of the number of visitors on Sundays=510×5=2550 -----(1)

Given that average number of visitors on other days is 240

Therefore, 240=25sum of the number of visitors on other days​

⟹sum of the number of visitors on other days=240×25=6000 -----(2)

Total average is 30total number of visitors​=302550+6000​=308550​=285

Therefore, the average number of visitors per day in a month of 30 days beginning with a Sunday is $285$

Explanation

Average of a , b = ( a + b ) /2

16a + 16b = 48

a + b = 3  || divide each term by 16

The average is ( a + b ) / 2 = 3/2

= 1.5

Explanation

A whole number is simply any positive number that does not include a fractional or decimal part.

This means that, for example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers.

Numbers such as -3, 2.7, or 3 ½ are not whole numbers.
