Question

Найдите значение выражения5 1/6-(1 7/9+a) , если а =1,5 Нужно решение (обязательно)

Answer 1

5 1/6-(1 7/9+a)=31/6-(16/9+3/2)=31/6-(32/18+27/18)=31/6-59/18=93/18-59/18=34/18=
1 8/9

Answer 2

Если а=1,5, то 5 1/6-(1 7/9+a)= 5 1/6-(1 7/9+1,5) = 5 3/18 - 1 14/18 - 1,5= 3 7/18 - 1,5 = 2 35/90 - 1 45/90 = 1 80/90  = 1 8/9

Answer 3

5 + 1/6 - (1 + 7/9 + a) = 5 + 1/6 - (1 + 7/9 + 1.5)

First, we need to add the fractions together: 5 + 1/6 - (1 + 7/9 + 1.5) = 5 + 1/6 - (1 + 63/54 + 27/18)

Now, we need to find a common denominator for the fractions: 5 + 1/6 - (1 + 63/54 + 27/18) = 5 + 1/6 - (1 + 42/36 + 27/18)

Now we can add the fractions together: 5 + 1/6 - (1 + 42/36 + 27/18) = 5 + 1/6 - (1 + 7/6 + 3/2)

Now we can combine the whole numbers and the fractions: 5 + 1/6 - (1 + 7/6 + 3/2) = 5 - 1 - 7/6 - 3/2

Now we can subtract the whole numbers and then subtract the fractions: 5 - 1 - 7/6 - 3/2 = 4 - 7/6 - 3/2 = 4 - 7/6 - 9/6 = 4 - 16/6 = 4 - 8/3 = 4 - 2 2/3 = 1 1/3

So, the value of the expression 5 + 1/6 - (1 + 7/9 + a), when a = 1.5, is 1 1/3.
