In a 3-digit number, the humdrends digit is one more than the ones digit and the tens digit is twice the hunderends digit. If the sum of the digits. Is. 11, find the number

362

Step-by-step explanation:

let the digits that make up the number be a, b and c with a in the hundred position, b in the tens and c in the units position. Given that

he hundreds digit is one more than the ones digit

a = c + 1

c = a - 1

and the tens digit is twice the hundreds digit

b = 2a

If the sum of the digits is 11

a + b + c = 11

substituting

a + 2a + a - 1 = 11

4a - 1 = 11

4a = 11 + 1

4a = 12

a = 12/4

= 3

recall that

c = a - 1 = 3 - 1 = 2

b = 2a = 2 * 3 = 6

Hence the number is 362

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
