Answer:

This statement will always be true practically.

Step-by-step explanation:

Let the odd number be:

=2x - 1

So the next odd will be:

= 2x + 1

Now for getting sum of two odd numbers we will add them:

= (2x -1)+(2x + 1)

Opening brackets:

= 2x -1 +2x +1

A dding like terms, Both 1's  will be cancelled out

= 4x

Now this proves that adding two odd numbers will deduce to a result which will always a multiple of 4

Hence proved.

I hope it will help you!

Divide ₹960 between Manu and Swapna in the ratio 5: 7
il63 [147K]

Ratio gives the fractional division of a whole into a given portion. Manu's will get 400 while Swapna will get 560.

To divide 960 in the ratio 5 : 7

  • Sum the ratio = (5 + 7) = 12
  • Manu's share = 5 × (960/12) = 400

  • Swapna's share = 7 × (960/12) = 560

Therefore, Manu and Swapna's share is 400 and 560 respectively.

Which number should follow in this series: 64/64 9/12 6/12​
zheka24 [161]

Answer: \frac{1}{4}

Step-by-step explanation:

You can reduce the fractions, then:

\frac{64}{64}=1

\frac{9}{12}=\frac{3}{4}

\frac{6}{12}=\frac{3}{6}=\frac{1}{2}

Rewrite them as following:

1,\frac{3}{4},\frac{1}{2}

If you subtract the first number and the second number, you obtain:

1-\frac{3}{4}=\frac{1}{4}

 If you subtract the second number and the second number, you obtain:

\frac{3}{4}-\frac{1}{2}=\frac{1}{4}

Therefore, you must subtract \frac{1}{2} and \frac{1}{4} to obtain the number asked. Then, this is:

\frac{1}{2}-\frac{1}{4}=\frac{1}{4}

(01.03) What number should be placed in the box to help complete the division calculation? (4 points) long division setup showin
Olin [163]

Answer:

i don't know if this is correct, but i think you place 2 in the box.

Step-by-step explanation:

you need to try to find the closetest multiple to find the division answer. so whichever one is closer is the one you need to use. mulitpy 2 to see if that's gets you anywhere, but something times 2 will get you 702. because if it ends in 2,4, or 6 it's a factor of 2. i hope this helps, but i'm not sure!
