Practice problem
What is another way to write 1a×1b\frac{1}{a}\times \frac{1}{b}a1×b1 when a,ba,ba,b are nonzero real numbers? (Choose all that apply.)
1b×a\frac{1}{b\times a}b×a1
a÷ba\div ba÷b
1a+b\frac{1}{a+b}a+b1
a÷(1b)a\div (\frac{1}{b})a÷(b1)
(1a)÷b(\frac{1}{a})\div b(a1)÷b
Type a concept, like “slope” or “photosynthesis”.
