The answer to these 2 questions would be:
1.
.8 is greater than .7.
or.
.7 is less than .8.
Why?
.8 is .1 higher than .7.
.7 + .1 = .8, so the greater than would be placed facing the .8.
2.
.8 is less than 7.
or.
7. is greater than .8.
Why?
You see where the decimal is placed at? It is placed after the 7 which makes the 7. a whole number. While .8 is still a decimal, 7. is way higher than .8 because of where the decimal is at.
This is how we get both our answers, 1. .8 and 2. 7.
Hope this helps!~
Let's get them to have a common denominator
2/3 and 3/4 are
8/12 and 9/12
clearly 8/12 will fit in 9/12 only once
so to simplify the fractions
2/3 fits in 3/4 only once
Hope this helps :)
