Question

(3\4+1\5)умножить5\19

Answer 1

1) (15+4)/20= 19/20
2) (19/20)*(5/19)=(19*5)/(20*19)=5/20=1/4

Answer 2

To solve this expression, we first need to simplify the terms inside the parentheses:

3/4 + 1/5 = (15/20 + 4/20) = 19/20

So, the expression becomes:

(19/20) * (5/19)

We can simplify this expression by canceling out the common factor of 19 in the numerator and denominator:

(19/20) * (5/19) = (1/4) * (1) = 1/4

Therefore, the solution to the expression (3/4+1/5)*5/19 is 1/4.
