Answer:
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
