Question

9,8 – 4,8 : (-0,65 – 0,25) =

Answer 1

Ответ:

$4 \frac{7}{15}$

Пошаговое объяснение:

$9.8 - 4.8 \div (( - 0.65) - 0.25) =$

$- 0.65 - 0.25 = - 0.9$

$- 4.8 \div ( - 0.9) = 4.8 \div 0.9 = 5 \frac{1}{3}$

$9.8 - 5 \frac{1}{3} = 9 \frac{8}{10} - 5 \frac{1}{3} = 4 \frac{24 - 10}{30} = 4 \frac{14}{30} = 4 \frac{7}{15}$

Answer 2

Пошаговое объяснение:

9,8-4,8:(-0,65-0,25)=

1) - 0,65-0,25= - 0,9

2) 4,8:(-0,9)= - 4 4/5:9/10= - 24/5×10/9=

= - 16/3= - 5 1/3

3) 9,8-(-5 1/3)=9 4/5+5 1/3=

=(9+5)+(12/15+5/15)=14+17/15=14+1 2/15=

=15 2/15

Answer 3

To solve the given expression, let's break it down step by step:

Step 1: Evaluate the expression within the parentheses (-0.65 - 0.25): -0.65 - 0.25 = -0.9

Step 2: Divide 4.8 by -0.9: 4.8 / -0.9 = -5.3333 (rounded to four decimal places)

Step 3: Subtract -5.3333 from 9.8: 9.8 - (-5.3333) = 9.8 + 5.3333 = 15.1333 (rounded to four decimal places)

Therefore, 9.8 – 4.8 : (-0.65 – 0.25) equals approximately 15.1333.
