Express the fractions 1/2, 3/16, and 7/8 with an LCD.

1 answer:

5 0

LCD stands for the least common denominator.
The least common multiple of the denominators can be calculated as follows;
denominators are 2,16 and 8
divide all by 2 2/2 = 1 16/2 = 8 8/2 = 4
Divide by 2 1 8/2 = 4 4/2 = 2
Divide by 2 1 4/2 = 2 2/2 = 1
Divide by 2 1 2/2 = 1 1
multiply - 2x2x2x2 = 16
16 is the least common multiple of 2,16 and 18
$\frac{1}{2}$ multiply both by 8 - $\frac{8}{16}$
$\frac{3}{16}$ as it is
$\frac{7}{8}$ multiply both by 2 - $\frac{14}{16}$
answer is 8/16,3/16,14/16

15% of Alina’s workout consisted of cardio exercise. 25% of Dane’s workout consisted of cardio exercise. Which statement must be

Arisa [49]

The correct answer is B. If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.

To figure this out, first find 15% of 80 and then 25% of 48.

To find 15% of 80, you can first find 10% of 80 which is 8(just move the decimal one place to the left). The remaining 5% will be half of 8 since 8 is 10%. Add both the numbers up and you will get 12. (8+4=12)

To find 25% of 48, you can divide 48 by 4. Since percent means 'out of 100', 25% is 25 of 100. 100 divided by 25 is equal to 4. So, 48 divided by 4 is equal to 12.

So, the final answer is B. They both equal to 12.
