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.
