Answer:

875

Step-by-step explanation:

As given, there is a three digit number

So, let assume three digit number be `xyz`.

Now, as given tens digit is 2 greater than the unit digit.

∴ y= 2+z

Next, the hundred digit one greater than the tens digit.

∴x= 1+y

The sum of the tens and the hundreds digits is three times the units digit.

∴x+y= 3z

Now, substituting the value in the equation.

x+y= 3z

⇒ (1+y)+y= 3\times (y-2)

solving it to get value of y

⇒ 2y+1= 3y-6

⇒-y= -7

∴ y=7

Next, finding value of z

y= 2+z

substituting the value of y and subtracting both side by 2

∴ z= 7-2= 5

Last, finding the value of x

x=1+y

substituting the value of y

∴ x= 8

xyz= 875

Nina [5.8K]

Answer:

24.11

Step-by-step explanation:

2001 ÷ 83

83×2= 166

200-166=34 bring down the 1

341 ÷ 83

83×4= 332

341-332=9 add a decimal and bring down a 0

90÷83

90-83=7 bring down another 0

70÷83=0 brind down another 0 since 70 cannot be divided by 83 and have a whole number

700÷83

83×8=664

700-664=36

right now you have 24.108

round to the nearest tenth
