Billy shaded 6/8 of a circle. mary shaded 15/16 of congruent circle. who shaded more. how do you know

6/8 = 12/16 which is less than 15/16

6/8=12/16so Mary shaded more

To determine who shaded more between Billy and Mary, we need to compare the fractions of the circles they shaded.

Billy shaded 6/8 of a circle, while Mary shaded 15/16 of a congruent circle.

To compare these fractions, we need to express them with a common denominator. The least common multiple (LCM) of 8 and 16 is 16.

Now, let's convert Billy's shaded fraction from 8 to 16 parts. To do this, we multiply the numerator and denominator by 2: 6/8 * 2/2 = 12/16.

Now that we have both fractions expressed with a common denominator, we can compare them:

Billy shaded 12/16 of the circle, while Mary shaded 15/16 of a congruent circle.

Comparing the two fractions, we can see that Mary shaded more of the circle because 15/16 is greater than 12/16.

Therefore, Mary shaded more of the congruent circle than Billy did.
