Answer

Problem

Is \$4/7\$ and \$12/21\$ equivalent to \$36/63\$?

Step

To find the greatest common divisor (GCD) for each number. Factors for 12 is
Factors for 21 is

1, 3, 13, 39
1, 3, 7, 21

Step

The GCD for 12 and 21 is 3
Divide both the numerator and the denominator by the GCD

\$(12 ÷ 3)/(21 ÷ 3) = 4/7\$

Step

Simplify this fraction by finding the GCD of 36 and 63, which is 9. + Divide both the numerator and denominator by 9:

\$(36 ÷ 9)/(63 ÷ 9) = 4/7\$

Step

Yes, \$4/7\$ and \$12/21\$ are the equivalent fractions of \$36/63\$

Answer

Option

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

This option is correct because \$4/7\$ and \$12/21\$ are the equivalent fractions of \$36/63\$

Yes

Choice.B

This option is incorrect because we have shown that \$36/63\$ simplifies to \$4/7\$, so they are equivalent fractions

Choice.C

This option is incorrect because option A is correct, while option B is incorrect

Both A & B

Choice.D

This option is incorrect because option A is correct as we have shown that \$36/63\$ simplifies to \$4/7\$ but option B is incorrect

None

Sumup

Can you summarize what you’ve understood in the above steps?
