Rewrite 0.7 as a common fraction

7/10

The larger the number in the denominator the smaller the fraction

Think of a pizza

You cut it into 9 slices. You cut another pizza into 10 slices. Which pizza has the bigger slices?

Take another 2 pizzas. Cut one into 4 slices and the other into 3 slices. Which pizza has the bigger slices? Compare the numbers in the denominators.

Another way of thinking about size Rewrite both numbers as common fractions.

0.7 = 7/10, 7/9

Find the common denominator

7/10 X 9/9 = 63/90

7/9 X 10/10 = 70/90

Which fraction is closer to 90/90?

0.7 = 7/10

If you had 7 pizzas and you divided then among 9 friends you'd get a bigger share than if you divided them among 10 friends.

Stated another way, if the numerators are the same, the larger the denominator the smaller the fraction (and vice versa).

7/9 > 7/10 (0.7)

The 0.7 is 7/10, and you are comparing it to 7/9.

Keeping in mind that 1/2 > 1/3 > 1/4 > 1/5 etc.,

you can see that 7/9 = 7 x 1/9 > 7 x 1/10 = 7/10.

So 7/9 is greater.

you have a calculator...

7/9 = 0.777

which is greater than 0.70

alternate:

compare 7/10 to 7/9

latter has smaller denominator, therefore fraction is larger.
