Question

(-789 3/5+(-101,4))+(-27,04+(-72 24/25))

Answer 1

запишем пример раскрыв скобки

-783 3/5-101,4 -27,04 - 72 24/25 = -991

что бы удобнее решать было скомпануем десятичные дроби и обычные

-789 3/5- 72 24/25=(-789-72) (-3/5)*5-24/25=-862 14/25

(-789-72) вынесла целые части ,для удобства

-101,4-27,04= -128.44

-862  14/25 -128,44=-862 14/25-128 44/100=(-862-128)(-14/25)*4-44/100=-991

(-862-128) это я вынесла целую часть для себя, мне так удобнее решать

Answer 2

To solve the expression, we need to perform the operations step by step. First, let's simplify the addition inside the parentheses:

-789 3/5 + (-101,4) = -789 3/5 - 101.4

Next, we simplify the addition in the second set of parentheses:

-27,04 + (-72 24/25) = -27,04 - 72 24/25

Now, let's add the two results together:

(-789 3/5 - 101.4) + (-27,04 - 72 24/25)

To add these fractions and decimals, it's often easier to convert them to a common format. Let's convert all fractions to decimals:

-789 3/5 = -789.6 (approximately) -72 24/25 = -72.96 (approximately)

Now the expression becomes:

(-789.6 - 101.4) + (-27.04 - 72.96)

Performing the operations within the parentheses:

-891 + (-100)

Finally, adding the two results together:

-891 - 100 = -991

So, the simplified result of the expression is -991.
