Answer 1

Ответ:

1.4

Объяснение:

$15*\frac{1}{5}-8*\frac{1}{5}=\frac{1}{5}*(15-8)=\frac{1}{5}*7=\frac{7}{5}=1\frac{2}{5}=1.4$

Answer 2

To solve the expression, you should follow the order of operations, which is typically represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right). In this case, there are no parentheses or exponents, so we'll perform multiplication and division from left to right:

1. Start with the multiplication:

   15 × (1/5) = 15/5 = 3

2. Next, perform the other multiplication:

   8 × (1/5) = 8/5

3. Finally, subtract the results:

   3 - (8/5)

Now, you need to subtract the fractions. To do this, you'll need to find a common denominator, which is 5 in this case:

3 - (8/5) = (15/5) - (8/5)

Now that the fractions have the same denominator, you can subtract the numerators:

(15/5) - (8/5) = (15 - 8) / 5 = 7/5

So, the final result of the expression is 7/5.
