Answer

Problem

What is the simplest form of a given fraction \$42/62\$.

Hint

To find the greatest common divisor (GCD) for each number..

Step

Factors for 42 is
Factors for 62 is

1, 2, 3, 6, 7, 14, 21, and 42
1, 2, 31, and 62

Step

The GCD for 42 and 62 is

Step

Divide both the numerator and the denominator by the GCD

\$(42 ÷ 2)/(62 ÷ 2)\$ = \$21/31\$

Step

So, after simplifying, we get \$21/31\$

Answer

Option

Sumup

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

Choice.A

This option is incorrect because it represents a different fraction than the one given

\$27/31\$

Choice.B

This option is incorrect because \$26/36\$ is not the simplified form of \$42/62\$

\$26/36\$

Choice.C

This option is correct. We have already determined that \$62/42\$ simplifies to \$21/31\$

\$21/31\$

Choice.D

This option needs to be corrected because, when we simplify \$42/62\$, it does not equal \$41/31\$

\$41/31\$

Sumup

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