Answer

Problem

Is the simplified fraction \$20/30\$ equivalent to \$2/3\$?

Step

To find the greatest common divisor (GCD) of the numerator and denominator:
Factors for 20:
Factors for 30:

1,4,5,10, and 20
1,5,6,10, and 30

Step

The greatest common divisor (GCD) of 20 and 30 is 10

Step

Dividing both the numerator and the denominator by 10, we get:

\$20/30 ÷ 10/10\$ = \$2/3\$

Step

So, yes, the simplified form of stem [20/30] is stem [2/3]

Answer

Option

This option is incorrect because the simplified fraction \$20/30\$ is indeed equivalent to \$2/3\$

Choice.B

This option is correct because \$20/30\$ simplifies to \$2/3\$

yes

Choice.C

This option is incorrect because option B is correct

Both A&B

Choice.D

This option suggests that neither fraction is equivalent to the other.
However, we established that the fractions are indeed equivalent. So, this option is incorrect

None
