Explanation

Length = 6m

Width = 5m

Height = 5m

Volume = L*W*H

=6*5*4

=120

Explanation

9.5 x 4 =38

Explanation

Multiply: 0.4 x 710 =​284

Explanation

The result of 340/50 is a terminating decimal with 1 digit to the right of the decimal point.

340 divided by 50 in decimal = 6.8

340 divided by 50 in fraction = 340/50

340 divided by 50 in percentage = 680%

Explanation

To convert 810/500 so you can write it as a decimal,

simply divide the numerator by the denominator, like this:

= 810/500

= 810 ÷ 500

= 1.62

Explanation

Explanation

Let: B= x   and A= 2x

(A+B) 18 days work = 1 

(A + B) one day work= 1/18

So:

x + 2x =1/18

⇒     x =  1/54 

So A=27 and B= 54

Explanation

Given: x = 3  

x³ = 3 × 3 × 3 = 27

Explanation

5 percent *5

= (5/100)*5

= (5*5)/100

= 25/100 = 0.25

Explanation

The sum of odd integers from 1 to 100 are - 1 + 3 + 5 + 7 + ……… + 99.

This is an Arithmetic Progression with the following parameters: First Number, a = 1 Last Number, l = 99 Common Difference, d = 2 So, the Number of terms in the Arithmetic Progression, n = (l - a)/d + 1 = (99 - 1)/2 + 1 = 98/2 + 1 = 49 + 1 = 50 So, the sum of the Arithmetic Progression, S = n/2(l + a) = 50/2(99 + 1) = 25 X 100 = 2500 So, the sum of odd integers from 1 to 100 = 2500
