How do you make the denominators of two fractions the same?

• Multiply the numerator and the denominator of each fraction by the denominator of the other fraction.
• Multiply just the denominator of each fraction by the denominator of the other fraction.
• Multiply the numerator and the denominator of each fraction by the numerator of the other fraction.
• Multiply just the denominator of each fraction by the numerator of the other fraction.

You have to solve the problem  
¾-⅛. After you make the denominators the same, what do you do?

• You subtract the numerators but keep the denominators the same.
• You subtract the numerators and you subtract the denominators.
• You subtract the denominators but keep the numerators the same.
• You subtract the numerator from the denominator, and that becomes the new numerator.
