on Serena's 10th birthday her mom was 3 times her age.How old will Serena and her mom be when her mom's age times 0.5 equals Ser
alex41 [277]
When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.

If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.

20 + 20 = 40
20 * 2 = 40

Serena will be 20, her mom will be 40.

Answer:

1. rational number

2. a positive rational number

Step-by-step explanation:

A rational number is a number that can be expressed as a simple fraction. When two rational numbers are multiplied together, the only logical answer would be for the outcome/product to also be rational.

The reciprocal of a positive rational number is also a positive rational number because if the original number was negative, the reciprocal would also be negative since the signs wouldn't change (in this case, the original number is positive). Since the original number is already a rational number, just by flipping it (the reciprocal), it would not change to an irrational, but instead stay the same.
