Question

15 * (1 + 1/3 - 1/5) Подробное решение :>

Answer 1

=15*1+15*1/3-15*1/5=15+5-3=17

Answer 2

Sure, let's solve the expression step-by-step:

1. First, let's simplify the expression inside the parentheses: 1 + 1/3 - 1/5

To add or subtract fractions, we need a common denominator. The common denominator for 3 and 5 is 15:

1 + (1/3)(5/5) - (1/5)(3/3) 1 + 5/15 - 3/15

Now, combine the numerators over the common denominator:

(1 + 5 - 3)/15 3/15

2. Now that we have simplified the expression inside the parentheses, we can continue with the multiplication:

   15 * (3/15)

To simplify, we can cancel out common factors between the numerator and denominator:

15/15

Finally, since any number divided by itself equals 1, the result is:

1

Therefore, 15 * (1 + 1/3 - 1/5) equals 1.
