Write the number 2.4 in the form a/b using integers
iragen [17]

Answer:

2\frac{4}{10}=\frac{24}{10}=\frac{12}{5}

Step-by-step explanation:

Here we have a number in the ones place, 2, and a number in the tenths place, 4.

  • Any number in front of the decimal becomes the whole number in front of the mixed number fraction
  • The numerator will be any number after the decimal
  • The denominator will be the value of the place the number after the decimal is in

Here our whole number is 2, the numerator is 4, and it is in the tenths place, so our denominator will be 10

Our fraction becomes 2\frac{4}{10} which then turns into the improper fraction \frac{24}{10} and then simplifying if needed becomes \frac{12}{5} after dividing the fraction by 2

The scale drawing was 90 to 18 units.

I hope this helps!
