Answer:
2 - 2y^2 - x/y
Step-by-step explanation:
2x^2/x^2 = 2
and
x^2/xy = x/y
therefore
2x^2/x^2 - y^2 - x^2/xy - y^2
= 2 - y^2 - x/y - y^2
= 2 - y^2 - y^2 - x/y
= 2 - 2y^2 - x/y
Step-by-step explanation:
100% = 96
1% = 100%/100 = 96/100 = 0.96
the temperature changed by 96 - 71 = 25.
how many % are these 25 ?
we check how often 1% fits into 25.
that is done by division :
25 / 0.96 = 26.04166667 ≈ 26%
