Question

By making x =1/3, y= -2/5 and x=1/4 find (x *y) + z

Answer 1

7/60

Explanation:

solution

(x*y) + z

(1/3*-2/5) + 1/4

-2/15 + 1/4

LCM 60

-8 + 15/60

7/60

Answer 2

7/60

Explanation:

Looking at the numbers:

x = 1/3

y = -2/5

z = 1/4

We can simply add them into the equation:
(x × y) + z

(1/3 × -2/5) + 1/4 =?

1/3 × -2/5 ≅ -0.1333333 or
`(-1333333)/(10000000)`

-0.1333333 + 1/4 = 0.1166667 or
`(7)/(60)`
