Question

3 7/24 +х=5 у-5 3/7= 1 6/7 8 4/9-m=3 7/9

Answer 1

Ответ:

1 ) 3 7 / 24 + х = 5 ;

3 + 7 / 24 + x = 5 ;

Известные значения переносим на одну сторону, а неизвестные на другую сторону. При переносе значений, их знаки меняются на противоположный знак. То есть получаем:

x = 5 - 3 - 7 / 24 ;

x = 2 - 7 / 24 ;

x = 1 + 1 - 7 / 24 ;

x = 1 + ( 24 - 7 ) / 24 ;

x = 1 целая 17 / 24

2.y - 5 3/7 = 1 6/7  

y=1 6/7+5 3/7

y=6 9/7

y=7 2/7

Ответ: 7 2/7

3. m=8 4/9-3 7/9

m=7 13/9-3 7/9

m=4 6/9

m=4 2/3

m= 4 2/3

Answer 3

Let's solve each equation step by step:

1. 3 7/24 + x = 5

To solve this equation, we need to isolate the variable x.

First, let's convert the mixed number 3 7/24 into an improper fraction: 3 7/24 = (3 * 24 + 7) / 24 = 79/24

Now, we can rewrite the equation: 79/24 + x = 5

To isolate x, we subtract 79/24 from both sides of the equation: x = 5 - 79/24

To simplify the right side of the equation, we find a common denominator: x = (5 * 24 - 79) / 24 x = (120 - 79) / 24 x = 41/24

Therefore, the solution to the equation is x = 41/24.

2. y - 5 3/7 = 1 6/7

First, let's convert the mixed numbers into improper fractions: 5 3/7 = (5 * 7 + 3) / 7 = 38/7 1 6/7 = (1 * 7 + 6) / 7 = 13/7

Now, we can rewrite the equation: y - 38/7 = 13/7

To isolate y, we add 38/7 to both sides of the equation: y = 13/7 + 38/7

To add the fractions, we find a common denominator: y = (13 + 38) / 7 y = 51/7

Therefore, the solution to the equation is y = 51/7.

3. 8 4/9 - m = 3 7/9

First, let's convert the mixed numbers into improper fractions: 8 4/9 = (8 * 9 + 4) / 9 = 76/9 3 7/9 = (3 * 9 + 7) / 9 = 34/9

Now, we can rewrite the equation: 76/9 - m = 34/9

To isolate m, we subtract 34/9 from both sides of the equation: m = 76/9 - 34/9

To subtract the fractions, we find a common denominator: m = (76 - 34) / 9 m = 42/9 m = 14/3

Therefore, the solution to the equation is m = 14/3.
