Answer:
![\frac{1}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B30%7D)
Step-by-step explanation:
Take it in steps. First, find 7/9+6. Then we'll find 8+6/3, and, finally, we'll divide the two answers.
1:
7/9+6 = 7/15
2:
8+6/3 = 14/3
3:
or ![\frac{7/15}{14/3}](https://tex.z-dn.net/?f=%5Cfrac%7B7%2F15%7D%7B14%2F3%7D)
Then take that in chunks: 7/14 and 15/3.
7/14 = 1/2
15/3 = 5/1
Use those to rewrite it as
.
1/5 = .2
2/3 ≈ .6667 so we'll keep writing it as 2/3
![\frac{\frac{.2}{2}}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B.2%7D%7B2%7D%7D%7B3%7D)
.2/2 = .1, so:
= ![\frac{1}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B30%7D)
Answer:
31
Step-by-step explanation:
To rationalise 7 + 3
, multiply by its conjugate
The conjugate of 7 + 3
is 7 - 3
, then
(7 + 3
)(7 - 3
) ← expand using FOIL
= 49 - 21
- 21
- (3
)²
= 49 - 18
= 31
