Dissolve 5 grams of salt in 51 grams of water to prepare salt water. What's the weight of salt in water? What's the weight of water in salt water?

5 / 51 of the weight of salt in water = 5 / 51
Water accounts for 51% of the weight of brine (5 + 51) = 51 / 56
If you don't understand this question, you can ask,

A cup of salt water, salt accounts for one fifth of the salt water, add 16 grams of salt, salt accounts for one fourth of the salt water, how many grams of the original salt water?
We need it today! Just formula, not equation!

16 / (1 / 3-1 / 4) = 192 G
192 / 4 = 48g
192 + 48 = 240g
It should be

A cup of salt water, salt accounts for 20% of the salt water, add 16 grams of salt, salt accounts for 25% of the salt water, how many grams of salt water?
Don't use equations!

The original water accounts for 1-20% = 80%, and then water accounts for 1-25% = 75%. Now the total weight is 80% / 75% = 16 / 15, and the original 16 ^ (16 / 15-1) = 16 ^ / 1 / 15 = 240g ~ if you agree with my answer, please click the [adopt as satisfactory answer] button in time ~ ~ the mobile phone questioner comments on the top right corner of the client, that is

9.2 minus the sum of X equal to 1 and one sixth of 0.9, find the solution of X prior equation

9.2-x=1(1/6)+0.9
X = 7 (2 / 15)

How much is one third plus one sixth plus one ninth

1/3+1/6+1/9
=6/18+3/18+2/18
=11/18

Seven eighths times seven plus three eighths, seven twelfth times six plus five twelfth times six, three fifths times five sixths

7/8×7+3/8
=(7+1)×3/8
=8×3/8
=3
7/12×6+5/12×6
=6×(7/12+5/12)
=6×1
=6
3/5×5/6
=3/6
=1/2

It is known that the circumference of the semicircle is 51.4cm. What is the diameter of the semicircle?

51.4 * 2 = 102.8 perimeter
Perimeter = 2 R
R = 102.8/2 is about 16.37

A semicircle has a radius of 5 cm and a circumference of several cm. A semicircle has a circumference of 51.4 cm and a diameter of several cm

The radius of a semicircle is 5cm and its circumference is 2 * 3.14 * 5 = 31.4cm
The circumference of a semicircle is 51.4cm, and its diameter is 51.4 / 3.14 = 16.4cm

Given that the circumference of a semicircle is 51.4 cm, how many cm is the diameter of the semicircle?

Hello!
Let the diameter be X
（51.4-X）×2=3.14X
102.8-2X=3.14X
-5.14X=-102.8
X=20
If it helps you, please accept it

Solving equation (X -- 40) multiplied by (1 + 1 / 3) = x (1 + 12 / 100)
Final answer 250

(x-40)(1+1/3)=x(1+12/100)
(4/3)x-160/3=(112/100)x
(4/3-112/100)x=160/3
(64/300)x=160/3
x=250
