What is 111 times 2

What is 111 times 2

111×2＝222.

A times b times a times 10 times b equals B times 111,

a*b*a*10*b=b*111
a*a*b*10=111
a*a*b=11.1
If you do not limit the conditions, there are infinitely many solutions. Happy every day!

9999 times 0.4 plus 8888 times 0.8

=1111*9*0.4+1111*8*0.8=1111*(3.6+6.4)=11110

If a + B = 23, then (a + 5) + (B + 4) equals ()

（a+5）+（b+4）=(a+b)+9=23+9=32

If a of B minus B equals 3 of 5, then a of B equals 3 of 5

It's 8 / 5,
(a-b)/b=3/5
Then 5 (a-b) - 3b is 5A = 8b, so a / b = 8 / 5

16 minus 1 equals 15, 25 minus 4 equals 21, and N is the rule

(k * 10 + n) - k = k * 10 + (n-k) this is the associative law of addition
Is there any other law?

X minus x times (69 / 14 minus x) equals 0. What is x equal to?

x-x(69/14 -x)=0 x-x(69-x/14)=0
x(1-69/14+x)=0 x[1-(69-x/14)]=0
x(-55/14+x)=0 x(x-55/14)=0
X = 0 or x = 55 / 14 x = 0 or x = 55

Calculation process of 42.6 △ 19 1.6 △ 1.8 5.3 △ 0.28

42.6÷19 =426/190=213/95
1.6÷1.8=16/18=8/9
5.3÷0.28=530/28=265/14

Calculate 1 / 2 (180 ° - 69 ° 42 ′) + 13 ° 28 ′ 40 ″ * 3

Original formula = 1 / 2 * 111 ° 18 '+ 13 ° 28 ′ 40 ″ * 3
=55°39'+40°26'
=96°5'

5 times of 1 x minus 4.8 is equal to 3.4. Find x 2. Less than 4 times of a number. The number of 5.4 is 7.4. Find this number 3. Five times of a number minus the product of 1.2 and 5,
