Answer:
[tex]77\div.77\cdot1[/tex]
Step-by-step explanation:
What we're basically looking for here are ways to get 100 using these numbers.
My immediate first thought was "can we divide the 7's by some 7's to get 100?"
I know that [tex]7 \div .7=10[/tex], so I had the idea to make it [tex]77 \div .77 = 100[/tex]. This means that we can use the number 7 four times in the equation [tex]77 \div .77=100[/tex].
However, we're still missing a 1 that we need to include. This is easy, we can just multiply [tex]77 \div .77[/tex] by 1.
So in conclusion, we get [tex]77 \div .77\cdot1[/tex]
Hope this helped!
