C. 85%
Set up the proportions
136/160 = ?/100
Then cross multiply.
100 x 136 = 13600
13600/160 = 85
Also you could use process of elimination. 296% wouldn’t work because that’s saying 136 is almost 3 times as many as 160. The other answers wouldn’t work because it’s clear that 136 is more than half of 160.
First change them to the same denominator....
2×3 6
__ = __
5×3 15
1×5 5
__ = __
3×5 15
6/15+ 5/15= 11/15.
So the sum is 11/15
The rule for multiplying similar bases with exponents is:
(a^b)*(a^c)=a^(b+c)
In this case you have:
(x^9)(x^2)
x^(9+2)
x^11
