When a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot,

Monica [59]

Answer:

When a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot, is called a <u><em>mixed fraction</em></u>.

Step-by-step explanation:

A fraction is a number that is obtained by dividing an integer into equal parts and is expressed as:

$\frac{numerator}{denominator}$

An improper fraction is a fraction in which the numerator, that is, the top number, is greater than or equal to the denominator, that is, the bottom number. In contrast, in proper fractions, the numerator is less than the denominator.

Improper fractions can be represented as mixed fractions. A mixed fraction represents a whole number and a proper fraction, in other words, it corresponds to the sum of a whole part plus a fractional part. In summary, mixed fractions are made up of an integer part and a fractional part.

So, <u><em>when a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot, is called a mixed fraction.</em></u>

A mini-lottery involves selecting 2 numbers between 1 and 10. What is the probability of correctly picking the two numbers?

Igoryamba

The probability of correctly picking the two numbers is 2/10.

<h3>What is the probability?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

The probability of correctly picking the two numbers = (numbers that have to be selected to win / total numbers)

2/10
