Question

1. 4/5 x - 3 3/4 x = 2 1/2

2. Q - 7 5/6 = 6 1/2


3. Find the product. Simplify if possible

-1/3 (8 1/7)

just in case you dont understand

negative 1 over 3 ( 8 1 over 7)
not 81 over 7 little help would be nice

Answer 1

1. 4x/5 - 15x/4 = 5/2
16x - 75x 50
---------- = ----
20 20

- 59x =50
x= -50/59

Answer 2

2. Q - 7 5/6 = 6 1/2
Q - (7x6+5)/6 = (6x2+1)/2
Q - 47/6 = 13/2
Q= 13/2 + 47/6 = 43/3 = 14 1/3

Answer 3

yea thanks everyone but i could never figure out number 3 just made my head hurt trying

Answer 4

Q -47/6 =13/2
Q = 13/2 + 47/6
Q = (39+47)/6
Q = 86/6 = 43/3

Answer 5

3. -1/3 (8 1/7)
= (-1/3) [(8x7+1)/7]
= (-1/3) (57/7)
= (-1)(57)/[(3x7)]
= -57 / 21 = -2 5/7

Answer 6

5/7 is not the answer it does not show that

Answer 7

nice work
