Answer:

A. 7605

Step-by-step explanation:

If a number is divisible by 9, it is also divisible by 3.

A number is divisible by 9 if the sum of its digits equals 9 or an integral multiple of 9.

A. 7605

7 + 6 + 0 + 5 = 18 (an integral multiple of 9) ; divisible by 9.

B. 7690

7 + 6 + 9 + 0 = 22 ; not divisible by 9

C. 5390

5 + 3 + 9 + 0 = 17 ; not divisible by 9

B. 4524

4 + 5 + 2 + 4 = 15 ; not divisible by 9

The only number divisible by 3 and 9 is 7605.

Can you please help me with 23 and 25 I do not understand!!! Please help
adell [148]

when you multiply a number by a value that's greater than 1, that number increases, for example 2 and then we multiply it like 2 * 3, clearly 2*3 is greater than 2.

now when you multiply a number  by a value that's lesser than 1, that number decreases, for example 2 and then we multiply it by something like 1/4, so 2 * 1/4 = 1/2, well, clearly 1/2 is smaller than 2, so 1/2 is a decreased value of 2.

23)

we have here 4/7, and then a product, well, the product is 4/7 and 9/10, however 9/10 is less than 1, recall 1 = 10/10, 9/10 is just a tiny bit less than 1.

because we're multiplying 4/7 by some amount less than 1, the product is a smaller value than 4/7, thus

 \bf \cfrac{4}{7}~~>~\left( \cfrac{9}{10}\times \cfrac{4}{7} \right)

25)

we have here 5/6 and we multiply it by 7/7, wait a minute!!! 7/7 = 1, we're really just multiplying 5/6 by 1 then, what does that give us?  well, 5/6 * 1  = 5/6, just the number itself,

\bf \cfrac{5}{6}~~=~\left( \cfrac{5}{6}\times \cfrac{7}{7} \right)
