Question

91/13*4= 60/15*9= 70/14*8 Помогите пж у нас дистант а калькулятора нет даже на компе

Answer 1

$\frac{91}{13} \times 4 = \frac{91 \times 4}{13} = \frac{364}{13} = 28$

$\frac{91}{13} \times 4 = 7 \times 4 = 28$

$\frac{60}{15} \times 9 = \frac{540}{15} = 36$

$\frac{60}{15} \times 9 = 4 \times 9 = 36$

$\frac{70}{14} \times 8 = \frac{70 \times 8}{14} = \frac{560}{14} = 40$

$\frac{70}{14} \times 8 = 5 \times 8 = 40$

Calculating Arithmetic Expressions

To solve the given arithmetic expressions, we can follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. 91/13*4 - First, perform the division: 91 divided by 13 equals 7. - Then, multiply the result by 4: 7 multiplied by 4 equals 28.

2. 60/15*9 - Again, start with the division: 60 divided by 15 equals 4. - Next, multiply the result by 9: 4 multiplied by 9 equals 36.

3. 70/14*8 - Begin with the division: 70 divided by 14 equals 5. - Then, multiply the result by 8: 5 multiplied by 8 equals 40.

So, the results of the given expressions are: - 91/13*4 = 28 - 60/15*9 = 36 - 70/14*8 = 40

Therefore, 91/13*4 = 28, 60/15*9 = 36, and 70/14*8 = 40.
