Question

Help me plz really need to get this done

Answer 1

3.3 
$6 \frac{7}{8} = \frac{55}{8}$

-1/8 - 55/8 = -56/8 = -7 

3.4 
(-4x7)/10 = -28/10  = -14/5

3.5
-19/2 ÷ 38/7  <=> -19/2 x 7/38 and simplify = -7/4

Answer 2

6)

-1/8  -  6    7/8

= - ( 1/8 +   6   7 /8)

= -(6  7/8 + 1/8)

=  -(6  +  (7 + 1)/8)

=  -(6  + 8/8) = -7

= -7 


8)

-4 * (7/10)

= -4*7/10

= -28/10                 2 into 28 is 14 and 2 into 10 is 5.

= -14/5  or -2.8

10)

-19/2 ÷  (38/7)

-19/2 * 7/38                19 into 19 is 1 and 19 into 38 is 2

-1/2 * 7/2

= -(7*1)/(2*2)

= -7/4

Hope this explains it.
