Question

A)1,8х=1 b)11/18x=1 v) 1 1/3y=1

Answer 1

Ответ:

а) 1,8х=1

х=10/18=5/9

б) 11/18х=1

х=18/11=1 7/11

в) 1 1/3у=1

у=3/4

Проверка:

5/9*1.8=1

1=1

11/18*18/11=1

1=1

4/3*3/4=1

1=1

Answer 2

It seems like you've provided three different equations, each of which is set equal to 1, and you're looking for the value of the variable in each equation. Let's solve each equation for its respective variable:

A) $1.8x = 1$ To solve for $x$, divide both sides of the equation by 1.8: $x = \frac{1}{1.8} = \frac{10}{18} = \frac{5}{9}$

B) $\frac{11}{18}x = 1$ To solve for $x$, multiply both sides of the equation by $\frac{18}{11}$: $x = \frac{18}{11}$

C) $1 \frac{1}{3}y = 1$ To solve for $y$, we need to first convert the mixed number to an improper fraction: $1 \frac{1}{3} = \frac{4}{3}$ Now the equation becomes: $\frac{4}{3}y = 1$ To solve for $y$, multiply both sides of the equation by $\frac{3}{4}$: $y = \frac{3}{4}$

So, the solutions are: A) $x = \frac{5}{9}$ B) $x = \frac{18}{11}$ C) $y = \frac{3}{4}$
