Find a number opposite to: a) the sum of 5/6 and 2/3 b) the difference between 6.2 and 5.8 c) the product of 1/15 and 1/16 d) the quotient of 4.9 and 3.5 plz bros its like 40 points or somethinf

a  = - 1  1/2

b   -.4

c   -1/240

d   -1 2/5

Step-by-step explanation:

a) the sum of 5/6 and 2/3  

5/6 + 2/3  

We need to get a common denominator

5/6 + 2/3*2/2 = 5/6 + 4/6 = 9/6

The opposite will give us 0 when added together

9/6 + -9/6 = 0

The opposite is -9/6

Simplifying -9/6 = -3/2 = -1 1/2

b) the difference between 6.2 and 5.8

6.2 - 5.8 =   .4

The opposite will give us 0 when added together

.4 + -.4 = 0

The opposite = -.4

c) the product of 1/15 and 1/16  

 1/15 * 1 /16 = 1/240

The opposite will give us zero when added together

1 /240  - 1/240 = 0

The opposite is - 1/240

d) the quotient of 4.9 and 3.5

 4.9 / 3.5  = 49/35 = 7/5  

The opposite will give us zero when added together

7/5 + -7/5 = 0

The opposite is - 7/5

Simplifying

-7/5 =  - 1 2/5
