What is the exact value of 5 5/6- (1 1/4 +3 7/8)
goblinko [34]

Answer:

15/40 which simplified is 3/8

Step-by-step explanation:

To solve this equation, we first have to turn all mixed numbers into improper fractions so we can add and subtract them

When we do this we get, 35/5 - (11/4 + 31/8)

Since there is a negative (-) sign before the parentheses, we automatically sub in a -1 in there and we distribute

Now we have 35/5 - 11/4 - 31/8

We can’t subtract this directly since they all have different denominators, so we have to change them to a common denominator

The common denominator of 5 4 and 8 is 40 so we multiply both the numerators and denominators by whatever number it is so the denominators are 40

This gets us to 280/40 - 110/40 - 155/40

When we subtract all of this, we get…

15/40 which can be simplified to 3/8

Hope this helped, have a great day, and please award brainliest

Solve the given equation
AlexFokin [52]
Eliminate the fractions by multiplying by least common multiple.
4,9,12 all go into 36 evenly. Multiply entire equation by 36.

36/4 = 9
36/9 = 4
36/12 = 3

New equation looks like:
9(w-1) +4(w+1) = -3(w+1) \\  \\ 9w -9 +4w +4 = -3w -3  \\  \\ 9w +4w+3w = -3 +9 -4 \\  \\ 16w = 2 \\  \\ w = \frac{2}{16} = \frac{1}{8}
